[molpro-user] transition dipole moment calculations

[Jayashree]

Hi all,
The transition between X state and A state of methoxy free radical is dipole
allowed, and I expect that the value of <2.1|DMZ|1.1> to be non-zero (in
fact, a sizeable number). Instead I find it to be almost zero (of the order
of 1.0e-8). Here is the input I am using and I would appreciate any comments
or suggestions for carrying out the transition dipole moment calculations
between the two states.

basis=6-311+G(2d,2p)
 geometry={Angstrom;
           c;
           o,c,oc;
           h1,c,h1c,o,h1co;
           h2,c,h2c,o,h2co,h1,dih1;
           h3,c,h3c,o,h3co,h1,dih2}
  oc=         1.39486910,
 h1c=         1.08983690,
 h2c=         1.08983690,
 h3c=         1.08983690,
h1co=       109.89813220,
h2co=       109.89813220,
h3co=       109.89813220,
dih1=       120.00000001,
dih2=       239.99999999

 {uhf;occ,7,2;open,7.1;wf,17,1,1}
 {casscf;maxiter,40;occ,9,3;closed,5,1;wf,17,1,1; state,1}
 {rs2;option,nstati=2}
 geometry={Angstrom;
           c;
           o,c,oc;
           h1,c,h1c,o,h1co;
           h2,c,h2c,o,h2co,h1,dih1;
           h3,c,h3c,o,h3co,h1,dih2}
 {casscf;maxiter,40;occ,9,3;closed,5,1;wf,17,2,1; state,1}
 {rs2;option,nstati=2}
 {casscf;maxiter,40;occ,9,3;closed,5,1;wf,17,2,1;
state,1;wf,17,1,1;state,2;tran,dm}
