An efficient theoretical method for investigating the cross sections and rate coefficients of electron impact excitation processes involving carbon monoxide (CO) diatomic molecules has been applied in the temperature range 1500–15 000 K. The weighted total cross section (WTCS) theory has been used to investigate the cross sections excitation of the a , a' , d , e , I and D states of CO. The 300 K cross sections as a function of electron energy and one temperature rate coefficients results are presented and fitting parameters (a, b and c) are given for each reaction rate coefficient: .
