I need help understanding analysis of mass spectrometry and UV, IR, NMR spectroscopy readouts. I'm looking up tutorials on websites and re-reading my textbook, and while I think I understand the
theory behind each method I'm drawing a blank when it comes to actually interpreting results to complete problems.

"Silicon based life" is a perennial sci-fi trope - I guess because silicon and carbon share similar-ish valency properties. Has anyone actually tried to flesh out what a silicon chemistry complex enough to support protein analogues would look like? Or more broadly, has anyone proposed schemata for complex, self-replicating chemistries that differ substantially from those we know?
