Optical frequency comb spectroscopy has proven an indispensable tool for high-resolution spectroscopy. QCL frequency combs offer the possibility to explore the mid-infrared spectral range. However, they suffer from large repetition frequencies which

Atmospheric methane is measured continuously from space, providing valuable information at global/regional scales for atmospheric monitoring as well as for surface flux estimates. However, as shown by several studies, CH4 atmospheric concentration re

Using a tunable diode-laser spectrometer adapted with a low temperature cell, we have measured the H2 line-mixing coefficients for 21 lines in the QR branch of the ν2 band and in the PP and RP branches of the ν4 band of phosphine (PH3) at low tempe
