Abstract:

Experimentally measured wavenumbers of rovibrational transitions of H³⁵Cl , H³⁷Cl , D³⁵Cl , D³⁷Cl molecules were used to find the parameters U_mj(m + j ≤ 4), Δ^H,_mj and Δ^Cl,_mj of HCl molecule invariant for any isotopic modification. Correlations between U_mj parameters were taken into account when estimating them. The isotopic-invariant parameters of potential in the Dunham and Simons-Parr-Finlan representations were calculated in terms of independent spectroscopic parameters U_m0 and U_m1 .
