Ethyl acetate has a carbonyl stretching absorption in the infra-red spectrum at 1742 cm-1. What is the frequency of the vibrational transition in Hz? (speed of light, C = 300,000,000 m/s)?

1742x100 x 300,000,000 = 5.226x10^13 Hz

100 is conversion factor from cm-1 to m-1

Frequency=c times 1742=5.226times 10^11 Hz.
