Study of the ν2 + ν10 Hybrid Band of the Trans-C2H2D2 Molecule

Resumo

The ν₂ + ν₁₀ (B_u) hybrid band of the trans-C₂H₂D₂ molecule in the region 2100–2300 cm^–1 is studied for the first time. The spectrum has been analyzed using the method of combination differences. Based on the obtained experimental data, about 900 \( \left({J}^{\mathrm{max}}=20\;\mathrm{and}\ {K}_a^{\mathrm{max}}=9\right) \) energy levels are assigned.
