Abstract

Rotational spectra in the v = 0, 1, 2, and 3 levels of the ground (¹Σ) state of sodium hydride have been observed using tunable far-infrared radiation generated from the difference frequency between two CO₂ lasers. The Dunham coefficients, which have been determined without the use of optical data or isotopic scaling relations, are Y₀₁ = 146 999.138(38) MHz, Y₀₂ = -10.29481(54) MHz, Y₀₃ = 6.243(49) × 10^-4 MHz, Y₁₁ = -4109.912(68) MHz, Y₁₂ = 0.14695(68) MHz, Y₂₁ = 33.341(34) MHz, Y₂₂ = -2.69(20) × 10^-3 MHz, and Y₃₁ = -1.0517(55) MHz. The constants are typically an order of magnitude more accurate than the best values previously available, and where comparison is possible, agreement is found to be excellent.
