The vibrational frequency of a bond is determined by the bond strength and the masses of the atoms involved, and this frequency is often unchanged (or nearly unchanged) by other atoms connected to the original group. Using the mathematical model of a harmonic oscillator, the quantized absorption of infrared radiation can be expressed as: v = 1/(2PIc) SQRT(k/u)
v is the reciprocal wavelength of the bond vibration
c is the velocity of light, k is the force constant ...
