Abstract
DURING the 1972 apparition of Jupiter we studied hydrogen quadrupole line intensities at the centre of the planetary disk, by observing the S(1) lines of the H2 (3–0) and (4–0) quadrupole bands which are respectively centred at 12268.8 and 15704.01 cm−1. These observations show that the abundance of hydrogen detected at these frequencies is extremely variable because of rapid changes in the structure of the visible clouds, which are confirmed by photographs of the planet.
