Abstract

The spectrum of neutral phosphorus has been studied in the infrared region 1-4 μm with the Fourier Transform Spectrometer at Laboratoire Aimé Cotton, Orsay, using a microwave-excited discharge tube as a light source. Altogether 538 transitions between P I levels have been measured and classified, 130 of which were resolved into hfs doublets. The results made it possible to confirm many new levels, established by transitions in the photographic region below 11 500 Å, and give adequate configuration assignments to the terms of the 3s3p4 and nd configurations.
