( 4 ) Question is in the photo below. PLEASE when answering, do not answer with HAND WRITING. Please TYPE the answer!

Hi sir Please solve question 13

The Infrared spectroscopic method solely can confirm the structure of a molecule. TRUE OR FALSE?

Please answer them. Thanks!

1,2

Stretching frequency Atomic mass of N || | = || |< |

Please answer all multiple choice don't justify just give me the answer

IR Spec: What is the relationship between vibrational frequency and mass of the atoms in the bond?

what would this molecule look like? I'm not sure I understand how to figure out what the molecule is made of.

Modified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. When a molecule absorbs light energy, its electron is excited raising its energy level. However, it does not stay there for long but it reverts back to its inactive state in which theelectron is at its lowest-energy level.

I'm confused on part 2-3 of the questions on the difference between infrared hymns and viable and how those photons are absorbed

IAH and IGH are not the answer.

At what wavelength does the molecule radiate from the excited state to the ground state? A. Shorter than absorbed radiationB. Longer than absorbed radiationC. A and B bothD. None

Give an example of fine structure from Infrared Spectroscopy. What information can you get from the fine structure in your example?

maximum 50 words

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

Answer correctly please

Discuss IR Spectroscopy theory: how does it work on a chemical level? What are the different regions of an IR spectra? What does it tell us about the molecule? 2.Discuss any chemical effects that may alter peak regions, specifically resonance.

Spectroscopy measures the interaction of molecules with electrical current. * O True False O O

Vibrational Spectroscopy When an atom in a bond is replaced with a different isotope of the same element, the reduced mass of the bonded atoms change the absorption of the vibration in the infrared (vibrational) spectrum. The wavenumber of a vibration is given by v = ¹, where k = force constant of the bond, μ = 2π reduced mass. Reduced Mass: μ = 1 " where m₁ and m2 are the mass of each attached atom. Assuming the force constant of a particular pair of atoms does not change when one or the other atom is substituted with an isotope, the magnitude of the vibrational shift can be determined from a ratio of the two vibrations. V₁ V₂ 1 k₁ 2π √1 1 k₂ 2π√√1₂ 1. An O-H stretch occurs at 3650 cm¹. What is the expected vibrational wavenumber of an O-D bond? 2. An NH3 stretch occurs at 3337 cm¹. At what wavenumber does the ND3 vibration occur? 3. An IR spectrum of a complex containing an Ru-O bond is depicted to the right. When 0-16 is substituted with 0-18, the vibration at 887 cm¹ appears to…

The correct answer is answer choice C. "A and B". I am not sure why - what is the thought process/concepts used? Thanks in advance.
