Gaussian09 計(jì)算 溶液中激發(fā)態(tài)的HOMO和LUMO,如何優(yōu)化結(jié)構(gòu)
|

1. 是否可以這樣優(yōu)化溶液中溶質(zhì)的激發(fā)態(tài)結(jié)構(gòu): 優(yōu)化基態(tài)結(jié)構(gòu)-----垂直激發(fā)-----優(yōu)化激發(fā)態(tài)機(jī)構(gòu) 2. 還是要像計(jì)算熒光光譜那樣,必須考慮溶液溶劑的穩(wěn)態(tài)和非穩(wěn)態(tài) 優(yōu)化基態(tài)結(jié)構(gòu)-----垂直激發(fā)------然后進(jìn)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 |
