Firstly, we adopt the same parametersthat well fit the Milky Way disk to the M31 disk evolution. We found thatthe obtained gas surface density and star formation rate profiles do notfit the M31's observation. This demonstrates that the star formation history inthe M31 disk may totally different from that in the Milky Way disk.

The B3LYP/6-31+G level of theory and the polarizable continuum model are employed to study the binding interactions between amidinium and tetrazolate anion which have two binding modes (side-on and end-on) as well as the binding interaction between amidinium and formate anion. We find, in the gas phase, that the end-on acetamidinium tetrazolate is more stable with its interaction energy 3.56 kJ/mol higher than that of the side-on.
