Concept explainers
Interpretation:
The given table has to be completed, in which nucleus require least energy and most energy.
Concept Introduction:
NMR Spectroscopy: NMR spectroscopy commonly known as MRI (Magnetic Resonance Spectroscopy), it is important Research tool of analysis for different organic molecule and its structures. (or) In other words hydrogen nuclei have spin (odd value) and all nuclei ae electrically charged. The extremal magnetic field is applied an some energy transfer is possible between the lower energy to excited level.
Spin state: The NMR is mosltly consult with nucleues spin quantum number
According to
Radio frequancy: The energy difference between the states is dependent upon the frequency. The expression is,
Here,
This frequency is dependent on the strength of the magnetic field and the gyromagnetic ratio. The expression is,
Here,

- the shielding in NMR is: a) Place a metal around the sample tube before staining it on the instrument.b) use a metal block to avoid being attacked by an opponentc) blocking the view of a participant in a concertd) when the magnetic moment of an atom blocks the induced magnetic moment of neighboring nucleiarrow_forwardExplained Answer for what happens when we approach Harrow_forward8. The energy difference between the a and 3 spin states for an 'H nucleus is the external magnetic field in which the nucleus is placed. (A) inversely proportional to (B) independent (C) directly proportional to (D) equal to the strength ofarrow_forward

Ohigh spin low spin cannot tell с. high spin low spin cannot tell Show Hintarrow_forwardProblem Which of the following nuclides would you predict to be stable and which radioactive: (a) 18/10Ne; (b) 32/16S; (c) 23/690Th; (d) 123/56Ba? Explain.Plan In order to evaluate the stability of each nuclide, we determine the N and Z values,the N/Z ratio from (A - Z )/Z, the value of Z, stable N/Z ratios (from as shown), and whether Z and N are even or odd.arrow_forwardA scientist investigates the possibility of neutron spin resonance, and has available a commercial NMR spectrometer operating at 300 MHz for 1H nuclei. What is the NMR frequency of the neutron in this spectrometer? What is the relative population difference at room temperature? Which is the lower energy spin state of the neutron?arrow_forward
