Notes:
A kinetic investigation of electronically excited arsenic atoms in the low-lying states, As(4p3 2DJ) and As(4p3 2PJ), ca. 1.33 and 2.28 eV, respectively, above the 44S3/2 ground state, has been carried out by atomic absorption spectroscopy. Atoms in these optically metastable states were generated by the pulsed irradiation of suitable arsenic compounds (AsMe3 for 2D and AsCl3 for 2P) in different spectral regions and monitored photoelectrically by time-resolved attenuation of atomic resonance radiation. Rate constants for the deactivation of these two states are reported for a range of collision partners. The data are compared with those of the analogous states of lighter atoms in group V, namely, P(32DJ, 32PJ) and N(22DJ, 22PJ), and discussed in terms of spin and orbital symmetry considerations.
