`TRANS`

The imaginary frequency due to the reaction vector in a
transition state calculation must not be included in the
thermochemical calculation. The number of genuine vibrations
considered can be:
3*N*-5 for a linear ground state system, 3*N*-6 for a
non-linear ground state system, or 3*N*-6 for a linear
transition-state complex, 3*N*-7 for a non-linear
transition-state complex.
This keyword must be used in conjunction with `THERMO` if
a transition state is being calculated.
