× If you have problems during the execution of MRCC, please attach the output with an adequate description of your case as well as the followings:
• the way mrcc was invoked
• the way build.mrcc was invoked
• the output of build.mrcc
• compiler version (for example: ifort -V, gfortran -v)
• blas/lapack versions
• as well as gcc and glibc versions

# CCSDTQ, multiplicity

1 year 2 weeks ago - 1 year 2 weeks ago #711
Dear mrcc users and developers,

I perform computations at CCSDTQ level by MRCC as standalone program. I see some inconsistency in CCSDTQ output:
 Number of alpha electrons:  7
Number of beta  electrons:  5
Spin multiplicity: 2
z-component of spin:  1.0
Spatial symmetry: 1
The printed value of multiplicity (2=dublet) is not in line (in my opinion) with 7 alpha nad 5 beta electrons.

Best wishes
Marcin

p.s. I use the last version (mrcc.2019-02-09.binary) of MRCC on Scientific Linux.
