| Abstract: | The hyperfine collisional processes of A-type CH3CN-H2 have been studied by the authors in the last paper. To complete the research work, the collisional transitional rate coefficients of E-type CH3CN-H2 are calculated under the conditions of interstellar molecular clouds in this continued paper, which presents many fundamental data for studying physical and chemical properties of molecular cloud and star forming region. |
