WHAT: A new way to look at chemical reactions
has been developed - the in situ study of the products
of a reaction by probing the vapor phase of that reaction with ISEELS
- electronic spectroscopy based on promotion of electrons from inner
shell to virtual valence levels. HBS is formed from reaction of H2S
flowing over hot boron crystals in a quartz tube. At elevated temperature
and pressures the H2S attacks the quartz, allowing
formation of HBO. This is the first observation of the B 1s core excitation
spectra of these unstable species.
