ABSTRACT
The HF/DF chemical lasers are based on the cold and hot pumping reactions: F + H 2 → HF ( v , J ) + H v = 1 , 2 , 3 34 kcal mol − 1 ‘ cold reaction ’ H + F 2 → HF ( v , J ) + H v = 1 − 8 102 kcal mol − 1 ‘ hot reaction ’ F + D 2 → DF ( v , J ) + H v = 1 , 2 , 3 , 4 34 kcal mol − 1 ‘ cold reaction ’ D + F 2 → DF ( v , J ) + F v = 2 − 9 102 kcal mol − 1 ‘ hot reaction ’ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003127130/2e64cbc3-301f-4eb2-9cf3-aa26985baf2f/content/C034_Eqn_0001.tif"/>
