✦ Synopsis

The sharp, weak absorption bands that overlay the descending tai! of the intense N-V absorption system of mans-1,3butadiene are shown to comprise a forbidden electronic transition that is made visible by viintions of the au symmetry species of the C2h symmetry group to which this molecule belongs.

negative ion lormation in ethylene and l,%butadicne has been studied using high resolution, ION, energy electron scattering. Sharp structure in the total electron scattering cross section allows the adiabatic electron affinity of each molecule to be determined Icadin\_e to values of -1.55 + 0.1 eV T
