Document Summary

Co2 and ch4 can be observed in ir because they can have asymmetrical stretching. The only thing that cannot be observed in ir: pure atom, homonuclear diatomic (no dipole moment) Nmr: same technology as mri (slightly different name) Protons and neutrons are engaged in self-rotation (spin) Mass number: the sum of proton number and neutron number. 12c and 16o are the most commonly isotope in nature not magnetic. Nucleus of 1h and 13c are very similar to electron (can spin up/down). Note: energy (speed up/down energy difference) is directly proportional to hv. Peaks in nmr only appears at single spikes lack peak shape/structure. Nmr observes the resonant frequency by applying an external field b0. Shielding: local magnetic field (of actual nucleus) is less than external field.
