| Abstract: | IOS(infinite order sudden) approximation,the hyperfine collisional transitional rate coefficients of E - type CH3CN - H2 have been calculated under the conditions of interstellar molecular clouds.The kinetic temperature is between 20 and 140K. The results present many fundamental data for studing physical and chemical properties of molecular cloud and star forming region. |
