Gun oscillator emits microwaves which are used as source in ESR. Klystron tube is one type of gun oscillator. For NMR spectroscopy, Rf oscillator is used which produces radio waves.
Number of hyperfine splitting can be given by formula 2nI + 1 where n is the number of equivalent nuclei and I is the spin quantum number of nuclei. So here, n=2 and I value for proton is ½ . So the number of peak splittings will be equal to 2(2)(1/2) + 1=3.
(C) Remains constant
(D) Either increases or decreases
Primary standard used in ESR is
(C) Tetramethyl silane
(D) Diphenyl hydrazyl
The ratio of peak splitting that can observed with three equivalent protons will be
