Complex susceptibility for collisional broadening
Abstract:
A unified approximate expression for the real part of the susceptibility for collisionally broadened transitions, including line coupling, has been developed. The Hilbert transform has been applied to the impact approximation line shape (Kramers-Kronig relationship) to obtain a result that is applicable from the microwave to the infrared. The approximate function has been compared numerically with the exact result using a newly developed algorithm. The results are applicable to spectral computations of the index of refraction and propagation delays.

¹H NMR: Interpreting Distorted and Overlapping Signals
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...

Longitudinal diffusion occurs when the solute molecules in the mobile phase diffuse from the more concentrated center of the chromatographic band to the more dilute regions on either side, both towards and against the flow direction. This...
Atomic Absorption Spectroscopy: Interference
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...
