How is a proton generator created? Hydrogen seems to be the easiest method, using He gas and an ionized attraction means. But has someone achieved this?
I have several Raman spectra with very distinct peaks at certain wavenumbers, such as 277, 359, 466, 583, 623, 686, and 795cm-1. How can I identify them to what compound(s)? The RRUFF and others...
