Measurement of the NH(3), CCl(2)F(2), CHClF(2), CFCl(3), and CClF(3) absorption coefficients at isotopic (13)C(16)O(2) laser wavelengths by photoacoustic spectroscopy.
Owing to the linearity of the photoacoustic signal, the absorption coefficients of Freons were measured on isotopic (13)C(16)O(2) laser lines.
