摘要

The spectral dynamics of a mid-infrared multimode Cr²⁺:ZnSe laser located in a vacuum sealed chamber containing acetylene at low pressure is analyzed by a stepping-mode high-resolution time-resolved Fourier transform interferometer. Doppler-limited absorption spectra of C2H2 in natural isotopic abundance are recorded around 4000 cm⁻¹ with kilometric absorption path lengths and sensitivities better than 3 10⁻⁸ cm⁻¹. Two cold bands are newly identified and assigned to the ν1+ν4¹ and ν3+ν5¹ transitions of ¹²C¹³CH2. The ν1+ν5¹ band of ¹²C2HD and fourteen ¹²C2H2 bands are observed, among which for the first time ν2+2ν4²+ν5⁻¹.
