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.
