About spectroscopy and instrumental analysis notes
GoConqr OriginalUsing Spectroscopy and Instrumental Analysis notes
These notes offer different ways into the unit. Introduction to Spectroscopy provides an overview, while Glossary brings together terms used in mass spectrometry. Start with the overview if you want context, or use the glossary when you need help with vocabulary.
For a closer look at a technique, H NMR Spectroscopy outlines an approach based on nuclear spin. The notes also include mass spectrometry, infrared spectroscopy and HPLC, so you can choose a topic that matches what you are studying.
Study one topic at a time
Read a short section, then write down its main terms and ideas in your own words. Return to the note to check what you remembered. If you want to see connections between ideas, switch to a mind map on the unit page; when you want to check your understanding, try a quiz there. Choose a technique and open a note that covers it.
Frequently asked questions
Which note should I start with?
Start with Introduction to Spectroscopy if you want an overview before choosing a technique. If you are already reading about mass spectrometry and need to check terminology, Glossary covers terms such as mass-to-charge ratio and abundance. Both are notes made by GoConqr users.
What topics do the notes cover?
The notes cover mass spectrometry, NMR, infrared spectroscopy and HPLC. Some focus on terminology or introductions, while others look at a particular technique. For example, H NMR Spectroscopy outlines nuclear spin, and NMR includes proton and carbon-13 NMR.
Are the notes free to use?
Yes. Every resource listed on this page is free to open and study without an account. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes. The listed resources were made by GoConqr users.
