Question

Calculate the wavenumber of stretching vibration of C=N.

Answer 1

Answer:

as we know that

= reduced mass = m1 ( mass of hydrogen ) =1 amu = 1.66 * 10-27 kg

mass of carbon = 12 amu = 12 * 1.66 * 10-27 Kg = 19.92 * 10-27 Kg

m1m2/m1+m2 = 1.66 * 10-27 * 19.92 * 10-27 / 1.66 * 10-27 + 19.92 * 10-27

= 33.067 * 10 -54 / 21.58 * 10-27 = 1.53 * 10-27

vibrational spectra of diatomic molecule --> = 1/2c (k / )1/2

where = adsorption frequency , c = speed of light in (cm) , k = force...
