[PDF] Wavenumbers and Frequencies - MSU chemistry PDF wavenumbers.pdf

since wavelengths are usually very small one often uses the nano meter (nm) m The frequency ν in the SI system is measured in reciprocal seconds 1 s − cm/m or 656 5 x 10 -7 cm or 1 523x10 4 cm -1 We can convert this to Hz by

Frequencies in IR are generally expressed in 1/ λ units; ie cm-1 since Infrared Spectroscopy E vib = (n+1/2)h(k/μ) 5/2 π where μ = m 1 m 2 /(m 1 +m 2 asymmetric NH2 stretches Wavenumbers, cm-1 500 1000 1500 2000 2500
