Sublimation dynamics of CO2 thin films: A high resolution diode laser study of quantum state resolved sticking coefficients
MJ Weida, JM Sperhac, DJ Nesbitt - The Journal of chemical physics, 1996 - pubs.aip.org
Nascent quantum states of CO2 subliming from CO2 thin films at rates of 1 to 103
monolayers (ML) per second are probed via direct infrared absorption of the ν3 asymmetric
stretch with a frequency ramped diode laser. The high spectral resolution (Δν≊ 15 MHz) of
the diode laser and the use of polarization modulation techniques permit individual
rotational, vibrational, translational, and even MJ degrees of freedom of the subliming flux to
be studied with quantum state resolution. Measured rotational and ν2 bend vibrational …
