New Skills

Knowledge - Level 1

know the terminology

spectroscopy, electromagnetic radiation, photon, frequency, wavelength, wavenumber, absorption spectrum, infrared, uv-visible, vibrational modes, fingerprint region, stretching frequencies, electronic energy, lambda max, NMR, nuclear spin, shielding/deshielding effects, chemical shift, TMS, ppm (delta), proton integration, spin-spin splitting, coupling constant, (n+1) rule, C-13 NMR, MRI


Concepts - Level 2

identify characteristics of electromagnetic radiation

identify types of molecular energy levels
and the types of radiation that stimulate transitions within those energy levels



Applications - Level 3

use IR tables to identify the presence or absence of various functional groups

predict whether a compound will show absorption in uv/visible

predict the number of peaks, their integrated area ratios, their approximate chemical shifts, and their spin-spin coupling patterns for a given compound in both H and C NMR spectra



Analytical Skills - Level 4 & higher

identify unknown compounds based on spectroscopic data
