The need for coupling heavy-particle excited-state kinetics and electr
on dynamics in molecular and atomic plasmas is illustrated for differe
nt plasma conditions, such as DC (direct current). RF (radio frequency
), laser pumping circuit, afterglow and multipole magnetic plasmas. Di
fferent systems (N-2, H-2, O-2, He, He-CO2 He-CO-CO2-N-2, SiH4, Ne-Xe-
HCl) are discussed with emphasis on the role of excited states in shap
ing the electron energy distribution function under various plasma con
ditions.
