Kurzfassung
The 12.6 mum region of nitryl chloride (ClNO2) has been recorded at high resolution (0.00102 cm-1) using a Fourier transform spectrometer and the SOLEIL synchrotron light source. ClNO2 was found during our studies of chlorine nitrate and, after fractional distillations it was introduced into a multipass White cell made of inert materials, with an optical path length of 5.4 m. 320 scans were recorded for the range 600-980 cm-1 at a total pressure of 0.23 hPa and a temperature of 250 K. A thorough analysis of the v2, 2v6 and 2v3 bands of 35ClNO2 and of the v2 band of 37ClNO2 falling in this region has been carried out using a Hamiltonian model which takes explicitly into account the numerous resonances affecting the ro-vibrational energy levels; especially the C-type Coriolis resonance between the v2 and the v3 +v6 modes. These two modes are only separated by less than 20 cm-1 and are thoroughly mixed. From the fittings, the following band centers were derived: v0(v2) = 792.761264(60) cm-1, v0(v3 +v6) = 775.8923(20) cm-1, v0(2v3) = 734.183576(20) cm-1 and v0(2v6) = 819.836727(90) cm-1 for 35ClNO2 and v0(v2) = 792.258284(30) cm-1 and v0(v3 +v6) = 774.6826(30) cm-1 for 37ClNO2 where the uncertainties are one standard deviation. Due to their sharp Q branches falling into an atmospheric "window", the detection of the v2 bands might be an advantageous route for future attempts to quantify atmospheric ClNO2, using infrared techniques.
