High‐resolution ν₁ spectrum of propyne: Application of a microcomputer‐controlled infrared‐acoustic color center laser spectrometer

Development of a microcomputer‐controlled infrared‐acoustic color center laser spectrometer capable of scanning in 100 cm⁻¹ sections over the wavelength range 2.2–3.3 μm with a resolution of 0.01 cm⁻¹ (300 MHz) is reported. Application of the spectrometer to investigation of the ν₁ spectrum of propyne is demonstrated.
