Investigation of the collisional energy transfer between excited-state NO X2Π1/2 (v = 3, 4) and CO via CARS spectroscopy.

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.
