Gallium hydride, GaH

Each stated uncertainty in this and other tables represents one estimated standard error, propagated to parameters from uncertainties of measurements of wave numbers the uncertainties of the latter measurements were provided by authors of papers [91,93] reporting those data, and the weight of each datum in the non-linear regression was taken as the reciprocal square of those uncertainties. As the reduced standard deviation of the fit was 0.92, so less than unity, the authors 

A factor Avogadro s constant multiplied by 10 enters these expressions on condition that atomic and electronic masses be expressed, as is customary in spectral analyses, in unified atomic mass unit both Uifi and f/o,i contain mass in their units, despite their values being formally independent of atomic mass. The standard errors associated with values of k and in Table 1 include contributions from errors of pertinent fundamental physical constants [94]. 

Of values in the right column of Table 1, the specified parameters are coefficients of z in formulae 45, 46 and 47, pertaining to vibrational and rotational g factors and adiabatic corrections respectively, with atomic centres B = Ga and A = H for this particular compound. Apart from the value of that was constrained to zero in the ultimate fit because preliminary fits indicated that its standard error much exceeded its magnitude, values of other parameters beyond cg, and Wg in their respective series, and also all and are not 

Production of an acceptable value of reduced standard deviation of a fit required multiple parameters m, up toj = 6. Values of these parameters with j 2 likely reflect not only adiabatic corrections their association with a particular term in 

Upon inverting formulae 59 and 60, we obtain these relations [89],
