Concentration measurements of ozone in the 1200-300ppbv range: an intercomparison between the BNM ultraviolet standard and infrared methods.

Simultaneous ultraviolet (UV) and infrared (IR) measurements of ozone concentration in air in the 1200-300 ppbv range have been performed using the ultraviolet absorption in the Hartley band at 0.2537 microm and the infrared absorption of a doublet at 9.507 microm in the nu(3) vibration-rotation band.

Diode-Laser Spectroscopy: Line Profiles of H(2)O in the Region of 1.39 &mgr;m.

Using a stabilized diode-laser spectrometer, we have studied the line profiles of water vapor near 7185.59 cm(-1). With low pressures of pure gas ( View Article and Find Full Text PDF
