A. Miklos et al., THE CO LASER PHOTOACOUSTIC ABSORPTION-SPECTRUM OF ISOPRENE - A REACTIVE BIOGENIC FOREST EMITTANT, Infrared physics, 34(6), 1993, pp. 635-640
The photoacoustic spectrum of isoprene vapor was measured in the 1740-
1870 cm-1 wavenumber range of the CO laser. Two distinct peaks found a
t 1740 and 1780 cm-1 appear suitable for monitoring isoprene concentra
tions of the air.
