Ir wavelength bands

WebOn the horizontal axis we see IR wavelengths expressed in terms of a unit called wavenumber (cm -1 ), which tells us how many waves fit into one centimeter. On the vertical axis we see ‘ % transmittance ’, which tells us how strongly light was absorbed at each frequency (100% transmittance means no absorption occurred at that frequency). WebAn absorption band is a range of wavelengths, ... the Wulf bands in the infrared beyond 700 nm, centered at 4,700, 9,600 and 14,100 nanometres, the latter being the most intense (named after Oliver R.
