Abstract

The infrared Fourier-transform spectrum of gaseous H2CNN (diazomethane) has been analysed between 800 and 250 wavenumber, at a spectral resolution 0.07 wavenumber. A preliminary analysis of the coarse and fine rotational structure of the three vibrational-rotational bands: ν5, ν6 and ν9 is reported. Using re structure rotational constant values, the vibration-rotation constants for the vibrational ground state are obtained as α(A)=+4018 MHz, α(B)= -34.78 MHz and α(C)=-15.23 MHz. A preliminary estimate for the Coriolis zeta coefficient (a-type) is |zeta(5,9)|= 0.91 and |zeta(6,9)| = 0.13.
