Instrument Notes

Light blue boxes are active links to my own notes.

You should also read the assigned material from the lecture text.

	Technique	Equipment Available	Sample Prep
	Cyclic voltammetry pp 190 – 191 of our lecture text	EG&G Princeton Applied Research Model 362 Scanning Potentiostat DATAQ A to D interface for data collection	Supporting electrolyte solution, prepare 10 mL in organic solvents: 0.1 M [NBu4][BF4] in water: 0.1 M KCl Need about 5 mg of sample
	Electron paramagnetic resonance (ESR, electron spin resonance) pp 181 – 183 of lecture text · H. A. Farach and C. P. Poole, Jr. provides an overview of the technique. · On-line EPR help from Natl. Inst. of Environmental Health Sciences (NIEHS) EPR research groups	Resonance Instruments Model 8400	Approximately 0.05 M solutions. Less polar solutions can be recorded in cylindrical quartz EPR tubes. More polar solutions must use flat quartz EPR cell.
	Nuclear magnetic resonance pp 177 – 181	Jeol ECX-300 FT-NMR	0.1 M solutions Can be run in protio solvents, although deuterated give good lock and shim.
	Infrared pp 175 – 177	Thermo Nicolet FTIR 100	as KBr pellets ATR attachment: allows direct spectra collection on bulk powders
	Electronic spectroscopy Ch 19 of the lecture text	Varian Cary 50	1 cm quartz cuvettes
	pp 463 – 465 of lecture text	Johnson-Matthey MSB-1 magnetic susceptibility balance	finely ground powder packed in glass tube about the same diameter as an NMR tube
	pp 185 – 187 of lecture text	Varian CP-3800 GC, Saturn 2200 MS
