How to read a NMR test or what does it say

This is the NMR test of GG's aztec crystal: https://anonimag.es/i/aztecb2596.png I dont understand anything sadly, i compared it to other NMR tests of LSD crystals ... there are minor differences, but how do i know whats better? Is there any "how the best possible NRM test should look like" out there?

here's my half-assed attempt at assigning the protons. it looks like they all match up but i can't guarantee i got the chemical shifts right. there should be an NMR reference for LSD somewhere on the internet.
*edit - the only signal missing is the indole nitrogen which may be downfield (higher ppm, off the scale) and I can't tell you what the non-integrated peak at ~4.75 ppm is without knowing the deuterated solvent

Go on JoR site. Beanbottle goes through all JoR xtal.

Usually for NMR one uses pure individual components. Purified by chromatography or crystallisation. GC-MS gives you the MWt. of each component but no structural info. as is the case for NMR. Some GC-MS packages come with a large compound database so it may spit a structure out at you. Ideally one uses them in tandem. For general identification the GC-MS with database may be an option for you.
