Coefficients of quantum numbers in the rotational @T06272@ expression and inversely proportional to the @P04848@. Symbols: \(A\), \(B\), \(C\). \(\overset{˜}{A}=\frac{h}{8\ \pi ^{2}\ c\ I_{\text{A}}}\) (dimension wavenumber), \(A=\frac{h}{8\ \pi ^{2}\ I_{\text{A}}}\) (dimension frequency) where \(h\) is the @P04685@ and \(c\) the speed of light in vacuum.
