WATER-VAPOR MEASUREMENTS BETWEEN 590 AND 2582 CM(-1) - LINE POSITIONSAND STRENGTHS

This study involves measurements of (H2O)-O-16, (H2O)-O-17, and (H2O)- O-18 vapor spectra for the region between 590 and 2582 cm(-1) The para meters derived from the data include line positions, energy levels, an d linestrengths. The study involves high-resolution line-position meas urements with samples at room temperature in the (000)-(000), (010)-(0 10), and (010)-(000) bands. The experimental frequencies were used alo ng with microwave, far-infrared, and hot water emission measurements i n an analysis to obtain high-accuracy rotational energy level values i n the (000), and (010) vibrational states of (H2O)-O-16 for J less tha n or equal to 20. The experimental linestrengths were fitted by least squares to a model in which the dipole moment was represented as a ser ies expansion containing up to 19 dipole moment matrix elements. The m easurements in this work were more extensive than reported in prior st udies by this author for the (010)-(000) band. (C) 1998 Academic Press .
