Vibrational Temperatures of Some Molecules in a Hollow Cathode Discharge

Abstract

Investigation of vibrational energy distributions of molecules excited in a hollow cathode discharge has been presented here. The vibrational temperatures of the CN, N₂ and N₂ ⁺ molecules have been measured at different experimental conditions. The excitation processes in HCD have been discussed.

Key Words:

• vibrational temperature
• hollow cathode
• excitation process
• N₂
• CN
