Abstract: The collision reaction that Kr(1Sg)+HF(X1Σ+;ν=1,2,3;J=4)→Kr(1Sg)+HF(X1Σ+;ν',J')has been studied using Monte-Carlo trajectory method,and it has been found that Kr atoms have in fluence on the fundamental and overtone vibrational frequency for HF(X1Σ+).The studying results show that,when the initial relative translational energy Et≤251.0kJ/mol,Kr atoms can reduce the particle number reversion of the fundamental vibrational frequency,and increase it of the overtone vibrational frequency,particularly in the energy level ν'=2,and Kr atoms are more strong on relaxing the higher rotational states(J'≥4).Thus,for hydrogen fluoride(HF)overtone frequency laser Kr atoms can obviously increase the strength of light and improve the transmission property in the air.
