Question

Arrange the following stretching vibrational modes in order of increasing the absorption wavenumber in IR spectra. A. 1, 2, 3, 4, 5 B. 4, 3, 2, 1, 5 C. 5, 3, 2, 1, 4 D 2, 3, 4, 5, 1 E. 2, 3, 3, 1, 5, 4 The coefficient of spontaneous emission increases with the wavelength of the transition. Collisional lifetime line broadening increases with the sample temperature. Natural lifetime broadening increases with the transition's wavelength. The magnetogyric ratio of^6Li is 3.9371 times 10^7 T^-1s^-1, Calculate the g-factor of this nucleus. A. 3.94 B. 0.822 C. 1.216 D. 0.656 times 10^7 E. 5.167

Explanation / Answer

1) the increasing order of wavenumber will be

C-I < C-Br < C-Cl < C=O < C-H

as the atoms become heavy the wavenumber decreases

2) False, It decreases with increase in wavelength

3) False, it decreases

4) True
