Monochromatic detection of plural rotational Raman spectra generated by multiple frequency excitation |
| abstract |
A method and apparatus for spectroscopic gas analysis are provided. Plural beams of monochromatic radiation are directed through gaseous material. A tuning mechanism adjusts the frequency difference between the radiation beams to equal substantially an odd integral submultiple of the frequency difference between adjacent spectral components of the periodic spectrum for a preselected constituent of the gaseous material. Radiation scattered by the gaseous material is received by a filtering mechanism adapted to transmit selectively a detectable signal composed of a single superimposed spectral component of the spectrum. The signal is received by a detecting means which indicates the intensity thereof. |
