[HTML][HTML] A state-selected continuous wave laser excitation method for determining CO2's rotational state distribution in a supersonic molecular beam

C Jansen, LBF Juurlink, R van Lent… - Review of Scientific …, 2024 - pubs.aip.org
State-resolved experiments can provide fundamental insight into the mechanisms behind
chemical reactions. Here, we describe our methods for characterizing state-resolved
experiments probing the outcome of the collision between CO 2 molecules and surfaces. We
create a molecular beam from a supersonic expansion that passes through an ultra-high
vacuum system. The CO 2 is vibrationally excited by a continuous wave infrared (IR) laser
using rapid adiabatic passage. We attenuate the fractional excitation using a CO 2 …
