An optoacoustic detector or spectrophone has been used to perform detailed measurements of the absorptivity of mixtures of water vapor in air. A C(12) O(2)(16) laser was used as the source, and measurements were made. at forty-nine different waveleng

In the present paper new results on the combustion of n-octane obtained by molecular beam mass spectrometry in a flat flame are presented. Corresponding experiments on i-octane have been reported [1] and comparisons to that compound are made to explo

A new mass spectrometer with modulated molecular beam, designed primarily for combustion studies in systems of research and practical interest, was built. Based on relevant physical models, new expressions for the useful signals generated are derived

An acoustically resonant opto-acoustic gas concentration detector is described. Experimentally obtained parameter values characterizing the detector are reported and comparison with the theoretically expected values gives a close agreement. A compara

Gaseous air pollutants can be detected by means of lasers in combination with an opto-acoustic detector. Different characteristics of such a laser-acoustic air pollution monitor, called here a spectrophone, are described. A test system is described b

It is pointed out that a theoretical expression used by Rosengren (see abstr. A18251 and B12654 of 1974), describing the pressure variations caused by radiation absorption, is only correct for monoatomic gases. With a correction factor introduced, th
