The lines have been reported by

1999, J. Chem. Phys. 110, 4797.
The λ spin-spin coupling value used here is already
the same as in

2002, J. Chem. Phys. 116, 5544.
The observed transitions cover N between 19 and 30.
Extrapolations to much lower or higher quantum numbers should be
taken with some care. Furthermore, for low N transitions
the 39K hyperfine splitting may be resolvable.
The dipole moment is not known. It may be considerably different
from the 4.1 D calculated for CaC (e052505.cat).
