List of tabulated asymmetric-top hfs parameters

All parameters of a given molecule are listed separately for each isotopologue and each vibrational state. Within this gross order, the hfs interaction constants are placed underneath the rotational parameters in columns 3 and 4. The following asyimnetric top hfs parameters are tabulated  

Components of the nuclear quadrupole couphng tensor in the inertial-axes system, in units of frequency (MHz, kHz), see eqs. (2.15, 2.16) 

Components of the nuclear quadmpole tensor in different axes systems as the principal axes of the field gradient tensor a,p,y) or the chemical-bond system x,y,z), or any other explicitly defined system 

Angle between specified axes, for example between a and the bond direction 

Cgg- or Mgg. spin-rotation coupling tensor elements of the indicated nucleus, in units of frequency 

Spin-rotation interaction strength of the rotational state Jxa c see eqs. (2.20a, 2.21a, 2.23a, 2.24). For remarks concerning the sign conventions of spin-rotation coupling constants, see the previous section 2.2.2 above.
