Bom Dia a todos.
Eu tenho um problema ao calcular Franck-Condon. Eu usei este cronograma


---- TRABALHO 1 ----
%Chk=S0.opt.chk
#P M06/6-31g** Opção

! Use o título correto e a especificação geom

---------------
---- JOB 2 ---- ! Use Root=2 para S0->S2
%Chk=S1.opt.chk
#P M06/6-31g** TD=(Raiz=1) Opção

! Use o título correto e a especificação geom

---------------


---- TRABALHO 3 ----
%OldChk=S0.opt.chk
%Chk=S0.frq.chk
#P M06/6-31g** Geom=Check Freq=(SaveNM,HPModes)

Título

! Multiplicidade de carga

---------------
---- TRABALHO 4 ----
%OldChk=S1.opt.chk
%Chk=S1.frq.chk
#P M06/6-31g** TD=(Root=1) Geom=Check Freq=(SaveNM,HPModes)

Título

! Multiplicidade de carga

---------------
---- TRABALHO 5 ----
%OldChk=S0.frq.chk
#P M06/6-31g** Geom=Verificar Freq=(ReadFC,ReadNM,ReadFCHT)

Cálculo Vibrônico

! Multiplicidade de carga

Imprimir=(Matriz=JK) ! Seção de opção L718

S1.frq.chk

---------------
Mas estou com o seguinte erro:
ERRO: Baixa progressão após a aula 2. Convergência total = 1,3%.
        O espectro vibrônico provavelmente não será confiável.


Como resolver este problema?

Sorry

Good morning everyone.
I have one problem when calculate Franck-Condon. I used this cronogram:

---- JOB 1 ----
%Chk=S0.opt.chk
#P M06/6-31g** Opt

! Use the right title and geom specification

---------------
---- JOB 2 ---- ! Use Root=2 for S0->S2
%Chk=S1.opt.chk
#P M06/6-31g** TD=(Root=1) Opt

! Use the right title and geom specification

---------------
---- JOB 3 ----
%OldChk=S0.opt.chk
%Chk=S0.frq.chk
#P M06/6-31g** Geom=Check Freq=(SaveNM,HPModes)

Title

! Charge Multiplicity

---------------
---- JOB 4 ----
%OldChk=S1.opt.chk
%Chk=S1.frq.chk
#P M06/6-31g** TD=(Root=1) Geom=Check Freq=(SaveNM,HPModes)

Title

! Charge Multiplicity

---------------
---- JOB 5 ----
%OldChk=S0.frq.chk
#P M06/6-31g** Geom=Check Freq=(ReadFC,ReadNM,ReadFCHT)

Vibronic Calculation

! Charge Multiplicity

Print=(Matrix=JK) ! L718 option section

S1.frq.chk
---------------

But I have the following error
ERROR: Low progression after class 2. Total convergence =  1.3%.
        The vibronic spectrum will likely be unreliable. Stopping.

How solve this problem?
