    The diffusion coefficient of O2 in H2O and D2O has been determined as a function of temperature from − to 95 °C, using the Taylor dispersion technique with optical absorbance detection at nm. Over this temperature range, significant deviation from both Arrhenius and Stokes−Einstein behavior is found. A practical interpolation formula for the H2O solvent is (T in Cited by: Request PDF | Diode laser measurements of temperature-dependent collisional-narrowing and broadening parameters of Ar-perturbed H2O transitions at and nm | High-resolution absorption.

    1. Introduction [2] One of the standard features studied in the terrestrial nightglow is the b 1 Σ g + − X 3 Σ g − system of oxygen, the O 2 Atmospheric bands. Until recently, only the 0‐1 band could be observed from the ground, where the typical zenith intensity is R.

    The study of LIG temporal evolution allows collisional relaxation rates of molecular excited states and gas temperature to be determined. In this work, the b{sup 1}{Sigma}{sub g}{sup +} state of O{sub 2} molecules deactivation rates are measured in a vol % H{sub 2} mixture at the number density of 2 amg in the temperature range K.   This book presents a comprehensive overview of the modern theory of spectral line broadening and shifting by pressure of atmospheric gases. It describes current semi-classical methods for calculating vibrotational line widths and shifts, including very recent modifications and new developments realised by the authors themselves.
