Absorption cross-sections off HFC-23 at atmospheric conditions

Spectral absorption cross-sections, kν (cm−1 atm−1), were measured in the 8.64 μm band system of HFC-23 using a high-resolution Fourier transform spectrometer. Temperature and total (N2-broadening) pressure were selected to represent atmospheric layers according to various atmospheric models. The measured absolute intensity (or integrated cross-section) was obtained to be 0.693±0.029×10−16 cm molecule−1.
