wavenumber cm 1 to m 1

In the SI system of units the wavelength λ is measured in meters (m) and since wavelengths are usually very small one often uses the nano meter (nm) which is  

Wavelengths in the mid-infrared are typically expressed in micrometers, commonly called microns, where one micron is 10-6 meters Another typical unit in the 

For the uninitiated, the spectroscopist's habit of using the unit cm¡ 1 for both frequency and energy is often corresponds to that wave number), for angular frequency, or for energy (i e the energy of a photon at that Wavelength ( m) 104§ ˜¢

Frequencies in IR are generally expressed in 1/ λ units; ie cm-1 since these are proportional to Infrared Spectroscopy E vib = (n+1/2)h(k/μ) 5/2 π where μ = m 1 m 2 /(m 1 +m 2 ) E rot = J(J+1)h Wavenumbers, cm-1 500 1000 1500
