| Abstract: | A diode laser spectrometer has been used for high accuracy H2O line profile measurements near 5475 cm−1. Measured lineshapes have been least-squares fitted by Voigt profile with a floating Gaussian component. Gaussian component pressure dependence resulting from the Dicke narrowing effect is observed. Line intensities, self- and air-induced broadenings, and shifts of five water vapor lines are presented. |
