ExoMol molecular line lists X: The spectrum of sodium hydride
MNRAS (accepted) 2015

The files comprising this line list are in the standard ExoMol format, and are
named XXNa-YYH__Rivlin.states and .trans, where XX and YY are the mass numbers 
ofthe Sodium and Hydrogen isotopes, respectively. The isotopologues covered
including their nuclear spin degeneracy factors g_ns are:  
(23Na)(1H) g_ns = 8
(23Na)(2H) g_ns = 12

The partition functions (bound states only) from 10 - 9000 K in 10 K intervals 
for these isotopologues of NaH are also provided in files named 
XXNa-YYH__Rivlin.pf and consist of two columns (T/K followed by Q).

The columns in the .states files are:
===============================================================================
XXNa-YYH_Rivlin.states
===============================================================================
i       I12     ---     state ID
E       F5.6    cm-1    state energy
gtot    I6      ---     total state degeneracy(1)
J       F5.1    ---     total angular momentum quantum number (excluding
                        nuclear spin)
X/A	s3	---	Electronic State
v       I4      ---     vibrational quantum number v
===============================================================================
(1) including nuclear spin degeneracy factors g_ns as above.   
(I(23Na) = 3/2, I(1H) = 1/2, I(2H) = 1)

The columns in the .trans files are:
===============================================================================
XXNa-YYH_Rivlin.trans
===============================================================================
i'      I12     ---     upper state ID
i"      I12     ---     lower state ID
A       ES10.4  s-1     Einstein A-factor
