Hello, i have a need to identify unknown substances. Ive been researching spectroscopy and and the various methods. I've read all about the different types and uses and I've settled on a uv/vis spectrophotometer as the instrument. i know its not 100% used for qualitative analysis but its good enough for my needs. my main question is, so i get a spectra output but id like to compare it to known substances to see what i have. I've seen tons of EXPENSIVE software to do this but I'm wondering if there is some open source or simpler way to do this. my budget is VERY limited, around a grand but i wanted to reach out and see what someone who knows more about spectroscopies thoughts are. I'm not a chemist, i have some knowledge but I'm motivated to learn. is this biting off too much or or is there something available that i just don't know about that can assist me in interpreting the data in simple way? thank you!
