[formula omitted]2Σ + → [formula omitted]2Π i emission spectra of the phosphaethyne cations HCP + and DCP

Electron impact excited A 2Σ + → X 2Π i emission spectra of HCP + and DCP + have been observed. The spectra consist of short progressions in ν″ 3. The 0 0 00 → 0 0 10 bands have been studied under high resolution and rotational analyses carried out. Some of the more important derived constants are (...

Description
Summary:Electron impact excited A 2Σ + → X 2Π i emission spectra of HCP + and DCP + have been observed. The spectra consist of short progressions in ν″ 3. The 0 0 00 → 0 0 10 bands have been studied under high resolution and rotational analyses carried out. Some of the more important derived constants are (in cm −1) HCP +; ν ″ 3 = 1150(10), A ″ 0 = -146.97(3), B ″ 0 = 0.6224(16), B ′ 0 = 0.6690(17); DCP +; ν ″ 3 = 1110(10), A ″ 0 = -146.71(1), B ″ 0 = 0.5284(2), B ′ 0 = 0.5682(2).
