Spectra of aromatic compounds look very different on old 60 MHz NMR instruments than they look at, say, a 400 MHz NMR instrument.  Have you tried applying any rules that you learned to monosubstituted rings?  If so, what did you learn?

I don't have specific thoughts regarding your question; I do, however, have a general comment.  Although we write nBuLi as if it were a simple, covalent compound, it aggregates in solution.

nBuli + H2O, and whether nBuli is a bronsted base?

This reaction-

n-BuLi + H2O → nBuH + LiOH

I understand is

C4H9Li + H2O --> C4H10 + LiOH

And I understand that n-Buli(C4H9Li)  is in a solvent but is not forming solvated ions. It's a molecule, it's covalent.

What i'm wondering is whether or not it's a bronsted base.
 
The conjugate pairs don't quite work..

C4H9Li/C4H10   <-- The Li has gone..

H2O/LiOH <-- An Li has been gained.

And we can't cancel the Li out as a spectator ion, because it's part of the n-Buli(C4H9Li) molecule, it's not a spectator ion.

Thanks

I guess it depends on your definition of "reaction".

TiO2 has photocatalytic properties and is frequently used for such, so you might start there.

It's more microbiology than chemistry... But don't people insert a gene into e-coli and express proteins this way? Do you want to use x-ray diffraction? Now it's common to use AI that looks at the primary structure and predicts the tertiary 3D-structure. Before when people used only x-ray diffraction it often took years to get good crystals from proteins, at Medivir we got crystals from HIV-reverse transcriptase and used x-ray diffraction. The x-rays were generated by an electron accelerator large as a football field and the crystals were cooled by ice the whole transport to the facility, it was not a simple job.
I don't find the paper, but this guy did the work I describe, here he is also working with HIV-RT: https://www.liebertpub.com/doi/abs/10.1089/aid.1990.6.1297
