小弟剛接觸gaussian,有幾個基礎(chǔ)問題想請教一下。 ------------------- - Thermochemistry - ------------------- Temperature 298.150 Kelvin. Pressure 1.00000 Atm. Atom 1 has atomic number 8 and mass 15.99491 Atom 2 has atomic number 1 and mass 1.00783 Atom 3 has atomic number 1 and mass 1.00783 Molecular mass: 18.01056 amu. Principal axes and moments of inertia in atomic units: 1 2 3 Eigenvalues -- 2.29432 4.17608 6.47040 X 0.00000 0.00000 1.00000 Y 1.00000 0.00000 0.00000 Z 0.00000 1.00000 0.00000 This molecule is an asymmetric top.
