Quantum numbers

The quantum numbers are given in the following order:
$J$ (or $N$); $K_a$ and $K_c$ (or $\pm$; $K$); $v$; $F_1$ ... $F$
for the upper state followed immediately by those for the lower state (see also below).

Very Important:

Exactly two characters are available for each quantum number. Therefore, half integer quanta are rounded up! In addition, capital letters are used to indicate quantum numbers larger than 99. E.g. A0 is 100, Z9 is 359. Small types are used to signal corresponding negative quantum numbers.

Since the program was written for asymmetric top molecules, some of the quantum numbers may be redundant.

Six quantum numbers are available at most to describe the upper and lower state, respectively. In case more quantum numbers are needed, even if some of them are redundant, the only spin designating quantum numbers are $n$, $F$, were $n$ is an aggregate spin number (see below).
