Wavenumber is calculated as,

$\overline{\mathbf{v}}\mathbf{\left(}{\mathbf{cm}}^{\mathbf{-}\mathbf{1}}\mathbf{\right)}\mathbf{=}\frac{\mathbf{1}}{\mathbf{wavelength}\mathbf{\left(}\mathbf{位}\mathbf{\right)}\mathbf{incm}}$

The units of wavenumber are cm^-1.

The units of wavelength are 碌m .

Since, 1 cm =10,000$渭m$

Wavenumber can be calculated by dividing 10,000 by the wavelength in microns.

An absorption of wavelength 3.40 碌m corresponds to a wavenumber that is calculated as:

$\begin{array}{rcl}\overline{v}\left({\text{cm}}^{\text{- 1}}\right)& =& \frac{10,000渭m/cm}{3.40渭m}\\ & =& 2941.17c{m}^{-1}\end{array}$

An absorption of wavelength 3.13 碌m corresponds to a wavenumber that is calculated as:

$\begin{array}{rcl}\overline{v}& =& \frac{10,000渭m/cm}{3.13渭m}\\ & =& 3095.97c{m}^{-1}\end{array}$

An absorption of wavelength 4.87 碌m corresponds to a wavenumber that is calculated as:

$\begin{array}{rcl}\overline{v}& =& \frac{10,000渭m/cm}{4.87渭m}\\ & =& 2053.38c{m}^{-1}\end{array}$

A wavenumber of 1800cm^-1 absorbs a wavelength that is calculated as:

$\begin{array}{rcl}位& =& \frac{10,000渭m/cm}{1800c{m}^{-1}}\\ & =& 5.55渭m\end{array}$

A wavenumber of 1670 cm^-1 absorbs a wavelength that is calculated as:

$\begin{array}{rcl}位& =& \frac{10,000渭m/cm}{1670c{m}^{-1}}\\ & =& 5.98渭m\end{array}$

A wavenumber of 1620cm^-1 absorbs the wavelength that is calculated as:

$\begin{array}{rcl}\mathrm{位}& =& \frac{10,000\mathrm{渭尘}/\mathrm{cm}}{1620{\mathrm{cm}}^{-1}}\\ & =& 6.17渭m\end{array}$
