The [formula omitted] electronic state of acetylene: Geometry and axis-switching effects

The geometrical parameters concerning acetylene in the A ̃ state are derived: r CC = 1.375 A ̊ , r CH = 1.097 A ̊ , and HCH = 122.48°. New rovibrational parameters of acetylene in the A ̃ state are provided or predicted. Axis-switching intensities are discussed on the basis of an extended formulatio...

Description
Summary:The geometrical parameters concerning acetylene in the A ̃ state are derived: r CC = 1.375 A ̊ , r CH = 1.097 A ̊ , and HCH = 122.48°. New rovibrational parameters of acetylene in the A ̃ state are provided or predicted. Axis-switching intensities are discussed on the basis of an extended formulation using the tensor algebra.
