3/27 Flashcards
what does the ground state describe
the lowest energy state
what is the zero point energy
it describes the lowest energy possible in the ground state
for a harmonic oscillator, is a molecule ever stationary?
no, it always has energy and vibrational frequency even in the ground state
is the difference in energy levels for a harmonic oscillator dependent on n?
no, the energy levels are evenly spaced
is the difference in energy levels for a particle in a box dependent on n?
yes, the energy levels are not evenly spaced and increase with n
compared to C=O, what is the force constant of C-O? what about frequency and wavenumber?
it will be smaller because the bond is weaker. The frequency will be lower and the wavenumber will be lower as well
what is the quantum number n?
it is principal quantum number
- it tells you about the size of the orbital (1s>2s)
- it tells you about the shell
n=1,2,3…
what is the quantum number l?
it is the angular quantum number, l=0,…,n-1, it tells you about the subshell
if l=0, what is the orbital?
it is s
if l=1 what is the orbital
it is p
if l=2 what is the orbital
it is d
if l =3 what is the orbital
3
what is the shape of the s orbital
sphere
what is the shape of the p orbital
dumbell
what is the shape of the d orbital
clover leaf
what is ml
it is the magnetic quantum number ml= -l,…, +l
it tells you about the orientation of the orbital
what is ms
it is the electron spin state, ms= +1/2 or -1/2
