    The effect of vibrational bond stretching on rotational inelastic electron-molecule scattering (1988)

    Notes: Abstract Differential cross sections for state-to-state rotationally inelastic electron-Na2 scattering, with the molecule being in the vibrational levelv′'=31, are measured at a collision energy of 150 eV. Angular momentum transfer of up to Δj=26 is observed, which is even more than previously obtained for the vibrational ground statev′'=0. Good agreement is found with theoretical results from a spectator scattering model. This work, in general, elucidates the role of vibrational excitation in collision dynamics under vibrationally sudden conditions.

    Gas chromatographic method to determine formaldehyde traces in automobile exhaust gases (1982)
    Springer
    Chromatographia 15 (1982), S. 631-634 
    Details
    ISSN: 1612-1112

    Notes: Summary A method for the gas chromatographic determination of traces of formaldehyde is described. The formaldehyde is detected by means of a modified FID which contains a microreactor inside the jet for the hydrogenation of formaldehyde to methane. Only a slight modification to an ordinary FID is needed with no additional gas tubes and no alteration to the existing detector heater. The additional dead volume and peak broadening is negligible. The system is calibrated by means of a gas generator. The described method is used for determining the content of formaldehyde in the exhaust gases of methanol-driven cars.
