Key Points

The aim is to investigate how collisional energy transfer between excited-state NO and CO varies with excitation energy and temperature.
Conducted experiments using CARS spectroscopy to measure collisional energy transfer.
Controlled sample cell temperature to assess its effect on relaxation rates.
Analyzed the relationship between excitation energy and relaxation rate coefficients.
The collision relaxation rate coefficient decreases with increasing excitation energy.
Relaxation rate coefficients significantly increase as temperature rises.

Implication
