#"Sublimation"# refers to the transition: #"solid "rarr" gas"#


Given a good enuff vacuum, and an efficient means to heat the solid (for example, a tube furnace), sublimation can often be performed on neutral molecules and complexes. Recoveries are generally low, but that which is collected, #"the sublimate"# tends to be very pure.
