We have observed the leading and trailing hemispheres of Phobos from 1.65 to 3.5 Β΅m and Deimos from 1.65 to 3.12 Β΅m near opposition. We find the trailing hemisphere of Phobos to be brighter than its leading hemisphere by 0.24 Β± 0.06 magnitude at 1.65 Β΅m and brighter than Deimos by 0.98 Β± 0.07 magnit
## Abstract **Lawesson reagent for selenium fans**: Phosphorus selenium heterocycles and, in particular, [PhPSe~2~]~2~ (known as Woollins' reagent) are proving valuable in the synthesis of new heterocycles and for the insertion of selenium into organic substrates. Incorporation of phosphorus and se
