[求助] Gaussian09 计算 溶液中激发态的HOMO和LUMO,如何优化结构

1.
是否可以这样优化溶液中溶质的激发态结构:
优化基态结构-----垂直激发-----优化激发态机构

2.
还是要像计算荧光光谱那样,必须考虑溶液溶剂的稳态和非稳态
优化基态结构-----垂直激发------然后进行:
State-specific solvation of the vertical excitation. This will require two job steps: first the ground state calculation is done, specifying NonEq=write in the PCM input section, in order to store the information about non-equilibrium solvation based on the ground state. Second, the actual state-specific calculation is done, reading in the necessary information for non-equilibrium solvation using NonEq=read.

%chk=03-ac
# B3LYP/6-31+G(d,p) SCRF=(Solvent=Ethanol,Read)
  Geom=Check Guess=Read

Acetaldehyde: prepare for state-specific non-eq solvation
by saving the solvent reaction field from the ground state

0 1

NonEq=write

--link1--
%chk=03-ac
# B3LYP/6-31+G(d,p) TD(NStates=6,Root=1)
  SCRF=(Solvent=Ethanol,StateSpecific,Read)
  Geom=Check Guess=Read

Acetaldehyde: read non-eq solvation from ground state and
compute energy of the first excited with the state-specific method

0 1

NonEq=read
