Research output: Contribution to journalArticlepeer-review


Absolute intensities have been measured for 26 lines of CH in the ν fundamental transition, using a tunable diode-laser spectrometer. These lines with 3≤J″≤21, 2≤K≤4, 2≤K≤20 are located in the spectral range 920-980 cm. The intensities have been measured by using two methods: the equivalent width method (EWM) and the line profile fit method (FPM). For the last one, three models have been tested: Voigt, Rautian and Galatry profiles.
