Relative wavenumber

WebIn vibrational spectroscopy, it is frequent to use the wavenumber ¯ν=1/λ (expressed in cm-1) instead of the angular frequency, so that the relative wavenumber Δ¯ν=1/λi−1/λs describes the Raman shift with respect of the laser line at 0 cm-1. In this case Equation (1) can be re-written as follows: ¯νs=¯νi∓¯νp (4) 2 WebThe wavenumber shift in SAR interferometry. Abstract: SAR surveys from separate passes show relative shifts of the ground wavenumber spectra that depend on the local slope and the off-nadir angle. The authors discuss the exploitation of this spectral shift for different applications: 1) generation of "low noise" interferograms benefiting phase ...
