NMR - Recall From Last Week
From 1H NMR, we get:
Chemical shift data () - This tells us what kinds of protons we have.
Integration data - This tells us the ratio of each kind of proton in our sample.
1H - 1H coupling data - This tells us about protons

Biocalorimetry allows direct measurement of enthalpy changes
associated with chemical reactions and processes.
Two main types of calorimetry are in widespread use
Magnetic Resonance Imaging
MRI is an application of nuclear
magnetic resonance spectroscopy
Some types of nuclei create magnetic
Most MRI techniques use 1H nuclei
Properties unique to magnetic nuclei
1) Non-zero angular moment
Optical Rotatory Dispersion (ORD), Circular Dichroism (CD) units and conversions
Specific Rotation: T = 100 /cl
(rot angle/path): = (1800/) x (nL-n R)
when c is in g/100mL and l is in dm, T in C is the wavelength of incident light.

As scientific professionals, you will be expected to explore new biochemical techniques on your
own, and then respond to questions about
NMR = Nuclear Magnetic Resonance
Some (but not all) nuclei, such as 1H, 13C, 19F, 31P have nuclear spin.
A spinning charge creates a magnetic moment, so these nuclei can be thought of
as tiny magnets.
If we place these nuclei in a mag

Mass spectrometry is an analytical technique used to identify
compounds by measuring the mass-to-charge ratio of ions. It is
most generally used to find the composition of a physical sample
by generating a mass spectrum representin
