What makes Nuclear Magnetic Resonance work?
Carbon 13
What is group 15 called?
Pnictogens
What is group 16 called?
Chalcogens
What is the Born-Oppenheimer approximation?
Electrons move so much faster than the nucleus that we can choose to ignore it when calculating
How do we calculate the energy emitted from an electron when it drops energy level?
E= R ((1/Ni^2)-(1/Nf^2))
What equation is used when calculating the energy of a certain bond? ej Carbonyl expressed in cm-1
E= CvHv (Change speed of light to cm-1)
What does the Schrodinger equation describe and the equation for it?
A partial differential equation that describes the change of the wavefunction of a physical system changes over time
What letter signifies quantum numbers and what does it stand for?
N describes the principal energy level of an electron
What is the solution to the 3D Schrodinger equation?
Electron orbitals
What is the Azimuthal number and how is it found?
The Azimuthal number is found by either the dictation of the orbital or N-1. The Azimuthal number, signified by l, tells us what orbital the electron is located in
What does the magnetic magnetic quuantum number reveal?
The orientation of the orbital and the electron found within
What does Psi and Psi squared stand for?
Psi signifiies the wavefunction of a physical system while Psi ^ 2 signifies the probability of electron being present.
What are all possible orientations for D orbitals?
dz^2 , 2x^2-y^2, dxy, dxz, dyz
What are all possible orientations for p orbitals?
px,py,pz
What does ungerade and gerade mean?
If the straight line that goes through the inversion center goes from phased to unphased then it ungerade. If the phases stay the same then it is gerade.
What does the magnetic spin symbolize?
The magnetic spin signifies the direction of the spin of the electron
What is the radial function?
The radial function described the distance away from the nucleus
