详细
A software-controlled photoacoustic spectrometer designed on the basis of a TEC-520 diode laser (output power 30 mW, coarse tuning range 6060–6600 cm−1, bandwidth ∼5 × 10–5 cm−1, fine tuning range is 0–2.5 cm−1), WS-UIR laser wavelength meter (relative error Δλ/λ ∼ 10–8), and resonance photoacoustic detector with a threshold sensitivity of ∼3 × 10–10 W cm−1 Hz−1/2 is described, as well as techniques and software developed for measurements and spectra processing. The water vapor spectra are analyzed.
