Specifically, the colour of a halogen, such as bromine, results from the electron transition between the highest occupied antibonding π g molecular orbital and the lowest vacant antibonding σ u molecular orbital. [36] The colour fades at low temperatures so that solid bromine at −195 °C is pale yellow. [32]
Bromine (35 Br) has two stable isotopes, 79 Br and 81 Br, and 35 known radioisotopes, the most stable of which is 77 Br, with a half-life of 57.036 hours.. Like the radioactive isotopes of iodine, radioisotopes of bromine, collectively radiobromine, can be used to label biomolecules for nuclear medicine; for example, the positron emitters 75 Br and 76 Br can be used for positron emission ...

In 1945, the standard FM broadcasting band was assigned to channels that started at 88.1 MHz. [6] [7] 87.9 MHz was added in 1978, as part of a project to improve use of the non-commercial channels of 88.1 to 91.9 MHz. 87.9 MHz was designated as a potential assignment for existing 10-watt "Class D" stations which were unable increase their power to at least 100 watts, and also could not be ...
