IInfrared Spectroscoy Flashcards
1
Q
Advantages of FTIR-ATR
A
High sensitivity
Extremely fast analysis Times
2
Q
What is the difference between a sp3 C-D stretch and an sp3 C-H
A
There will be a difference in the frencqucies of these two molecules since D is heaveir then H. Mass affects the freqncuey rate. in other words C-D will be lower then C-H sp3 bonds
3
Q
Common methods of sample preparation for a solid sample in infrared spectroscpy
A
Mulling
KBr pellets
NaCl salt plates
4
Q
In IR spectroscepy, if you doulbe the wave number you_____ the energy
A
double the engergy
5
Q
impacts of mass, bonds, and polarilty in IR.
A
The bigger the mass the less the molecule with vibrate.
The stronger the bond the less the bond will vibrate
if the more polar the bond is the more intense the virbation will be.
