Nuclear Magnetic Resonance Spectroscopy

The purpose of this experiment is to determine the maximum absorbance of fast green, and the chlorophylls, also in the case of fast green create a concentration curve to determine an unknown substance. Each test will use the spectrophotometer.

The unknown NMR/IR Unknown #7 was C8H11N. The first in determining the structure from looking at the NMR spectra was to determine the degrees of saturation (DoU). DoU helps identify the number of bonds within the compound. The DoU can be determined by looking at the chemical formula and using the equation, DoU= (2C + 2 + N - X – H)/ (2). For this particular compound, I identified that the DoU was 4. Next, using the given IR peak, as well as looking at the chemical formula, the weak wavelength of 3400 cm-1 was identified as a amine function group, and that particular peak was a N-H bond stretch. Next the NMR spectra was examined. Using the spectra, I noticed there were four different peaks, The first peak was a singlet around 7.3-7.3 ppm and only had one hydrogen on the compound.

MRI uses the body’s natural magnetic properties to formulate an image of the soft tissues. It does this by using the hydrogen atom nucleus which has a single proton and is a spinning charged particle. The human body is made up of 70% water, which is hydrogen and oxygen. Those hydrogen nuclei (protons) spin inside the body, creating their own magnetic field. They are orientated randomly and cancel each other out when no field is applied.

An MRI uses computer-generated radio waves and a strong magnetic field to produce a detailed image of the brain. “MRIs are helpful in the diagnosis of tumors, eye diseases, infections, inflammation, and damage due to head injury” (Hill 2008). When getting an MRI, you lay on a table that slides into a tube, and they use computer-generated radio waves and a very strong magnetic field to see images of the brain. This test will allow the doctor to see two and three-dimensional images of your brain.

MRI provides both anatomic and physiologic information. It is the modality of choice when cartilage, nerves, or organs are of interest. Magnetic resonance imaging does not give off any ionizing radiation. Instead, the magnetic force reacts with the hydrogen in our bodies to show the images. Because of this fact, it is the least harmful to the patient.

Plasma is often found in areas of the planet/universe where extremely high heats are possible and gases exist to help create the plasma.

Marc Janoschek (http://www.lanl.gov/discover/news-stories-archive/2014/November/janoschek-wolfram-prandl-prize.php) of the Los Alamos Lab says that, on the atomic level, each atom of a metal has a set number of electrons that orbit the nucleus that never changes. This set number of electrons is referred to as the metal in its ‘ground state’. The neutrons and electrons both have a magnetic field that creates an opportunity for the atom to be aligned in another magnetic field.

We have been given a new type of Magnetic Resonance Imaging (MRI) machine that will be available at our healthcare facility. As everyone knows an MRI machine is a non-invasive imaging technology machine that will help detect diseases in the brain, spinal cord and even soft tissues such as muscles, tendons (NIH, 2015). We need to organize a team that will oversee the education of the staff on how to use the machine. Then we need to figure out how we are going to educate the public on the machine and how it will benefit everyone. We need to have goals, timeframes as well. We also need to figure out the best forms of communication that we would use to get the information to the public as well as within our timeframe for the roll out of this new

An MRI consists of multiple powerful magnets which cause the atoms to resonate within the body. The nuclei produce their very own magnetic field which is able to be picked up by scanners and then turned into pictures for easier study and documentation. Since the body is mostly made up of water, the hydrogen atoms are able to align once the magnets are turned on in the machine. Two of the most popular MRIs would be the Functional MRI which studies the blood flow to the brain, while the Diffusion MRI studies the water molecules and how they diffuse throughout the body

Magnetic Resonance Imaging is also known as MRI. This computerized device is used for scanning the

Radiotracers help doctors diagnose and evaluate the degree of severity of the disease. The tracers are injected, swallowed, or inhaled. Special cameras used by the doctor to detect molecular information then detect the emissions from the radiotracers. One of the most important procedures in nuclear medicine is the MRI, or the magnetic resonance

Magnetic resonance imaging (MRI) is a scan used for a medical imaging procedure. With the use of a magnetic field and radio waves, an MRI scan takes pictures of the inside of the patient’s body. An MRI scan is particularly useful when images of soft tissue such as organs and muscles that do not generally appear on x-ray examinations need to be collected. X-rays generally image calcium present in bones, so they are useful to image bones. MRI scans image water as opposed to other diagnostic tools including X-rays or CAT scans. Thus, this makes them useful because every tissue of the body has various amounts of water present. This allows high-resolution pictures of numerous amounts of organs and tissues to be produced particularly of areas that

The MRI is possible in the human body because our bodies are filled with small biological ?magnets?, the most abundant and responsive of these are the protons. The principal of the MRI is that it utilizes the random distribution of protons, which have basic magnetic properties. Once the patient is placed in the cylindrical magnet, the diagnosis process follows 3 steps. First, MRI

Furthermore, in this experiment we learned that NMR takes advantage of the magnetic properties of the 1H and 13C nuclei. We are not concerned with 12C because it does not have a magnetic

An MRI (magnetic resonance imaging) is a scan that uses a system of techniques, involving magnetism, radio waves and a computer to generate detailed images of the human body. Essentially, it is a tube encased by a large circular magnet. The patient would be placed on a moveable bed, which is then inserted into the tube. The magnet then creates a strong magnetic field that aligns the protons of hydrogen atoms. These hydrogen atoms come from the human body, which is 50-65% H2O. These atoms are exposed to a beam of radio waves. This spins the various protons of the body. As they spin, they produce a slight
