[molpro-user] Energy doesn't match wrt to opt and Freq for BH2 radical in SA-CASSCF

[t s venkatesan]

Hi,

I am doing a SA-CASSCF optimization and frequency calculation for BH2
radical. Unfortunately, the total energy doesn't seem to match. Or may be i
am doing something wrong which i couldn't figure out myself. Here below are
the part of my input and output information. Any help would be appreciated.

***BH2 sa2-cas-fvas-optimization. a1 and b1 states are averaged
memory,200,m
gexpec,dm,qm
cartesian
basis={
spd,h,avtz;
spdf,b,avtz}

symmetry,x,z;
geometry={angstrom;
h1
b h1 r1
h2 b r1 h1 a1}

r1= 1.18742314
a1=120.

{hf;wf,6,1,0} !starting wf is cation

{multi;CPMCSCF,GRAD,STATE=1.1;
orbprint,5;print,civector;
wf,7,1,1;
wf,7,2,1}
