Abstract

A detailed examination of a high-resolution Fourier-transform spectrum of a platinum hollow-cathode discharge in the near infrared has yielded one Pt I and four Pt II parity-forbidden magnetic dipole transitions. Theoretical calculations and analysis of the hyperfine structure are used to confirm these assignments, and applications to astrophysics and lasers are suggested.
