Diatomic fluorine was reacted in a low pressure flame with selenium at
oms, generated by a microwave discharge in argon seeded with Se-2, and
the products were trapped in solid argon; new infrared absorptions we
re found at 677.0 and 680.4 cm(-1) for (SeF)-Se-80-F-19 and (SeF)-Se-7
6-F-19, respectively.
