Question

relationship between wavelength and wavenumber​

Answer 1

Answer

Answer

You can convert wavelength into wavenumber by simply dividing 10,000 by the wavelength expressed in micrometers. For example, wavelength of 10 micrometer is 10,000/10 = 1,000 cm-1. Using the FT-IR spectrometer, the spectrum is already expressed in the wavenumber. You do not need to do anything.
