See Making an Asymmetric Top Data File
for an introduction.
PGOPHER will
calculate
rotational structure for asymmetric
tops for the point groups C_{1}, C_{i}, C_{2},
C_{s},
D_{2}, C_{2v}, C_{2h} or D_{2h},
including effects due to electron and nuclear spin.
J 
Total angular momentum
excluding
nuclear spin 
N 
The rotational angular
momentum (excluding electron and nuclear spin). J =
N
+ S 
K_{a} 
The projection of N on to the a inertial axis; see Symmetry and Axis System 
K_{c}  The projection of N on to the c inertial axis. 
K 
The projection of N onto the inertial
axis determined
by the representation.

where Name is the
manifold and state name and J,
N and K
are the quantum numbers described above. N is ommited for singlet
states.
If + or  is
present, it implies the basis state is the symmetised combination:
If hyperfine structure is included in the calculation then F (and intermediate quantum numbers if there is more than one nucleus) is added to the end. If PhaseAdjust is set, then these functions are multiplied by an additional phase factor to minimize the number of imaginary matrix elements:
