> 10^-1 m
Holly feels sick and her head and body start spinning. She is in this part of Spectra-land.
What is radiofrequency?
Holly feels a force that makes her start doing cartwheels uncontrollably. She is in this part of Spectra-land.
What is microwave?
Holly feels cold and starts shaking uncontrollably. One could say she is vibrating. She is in this part of Spectra-land.
what is IR?
A ray of sunlight shines upon Holly the HCl and suddenly all her nearby friends feel energized and begin to move further away from Holly.
She is in this part of Spectra-land.
What is UV/Vis and beyond?
Holly is doing some homework and she wants to solve the Schrodinger equation. This is what we call, generally, the solution to...
What is an eigenstate?
Holly has an odd number of protons in both her H and Cl nuclei. When she steps into a magnetic field, she will experience this type of angular momentum of her nuclei.
What is nuclear spin?
When Holly changes her rotational energy level, the change in her rotational quantum number must follow this rule.
what is selection rule:
change in J = (+/-) 1
When Holly changes her vibrational energy level, the change in her rotational quantum number must follow this rule.
What is selection rule:
change in V = (+/-) 1
And must have a dipole
Holly’s mom wants to know where Holly’s friend Molly is. Molly’s position is currently described as a combination of several different places, but once Holly’s mom measures Molly’s position, Molly can only be in one of those places. Molly’s position is now well-defined.
What is the collapse of a wavefunction?
This is what is approximated by what Holly calls her linear combination of H and Cl atomic orbitals.
What are molecular orbitals?
Typically Holly feels all the different forces in the rest of Spectra-land, but only this force when she steps foot into it. This land is special compared to other parts of Spectra land.
What is the magnetic field?
While Holly is doing cartwheels, she feels this type of resistance property during her rotation.
What is the moment of inertia?
Holly’s vibrational motions can be modeled by the harmonic oscillator. The harmonic oscillator assumes that the energy of Holly’s vibrational motions are all evenly spaced out. In reality, however, the energies of Holly’s vibrational motions are closer together than modeled, especially as they get higher in energy.
What is anharmonicity?
Holly’s mom currently knows where Molly, Holly’s friend, is located. Holly’s mom is now unsure about what Molly’s energy is.
What is uncertainty?
This is the term that describes the likelihood of finding an observable on Holly.
What is probability?
Holly needs to use a method to approximate the wavefunction of an atom. She comes across a computer with a Gaussian program installed, which conveniently uses this method that treats the electron in the average field of others. However, this method also overestimates Holly’s energy.
What is Hartree-Fock?
When Holly is vibrating her dipole moment changes as opposed to her friend H2, who lacks a dipole moment.
What is IR active?
Molly, Holly’s friend, when energized by a ray of sunlight, can move away from Holly and have her position be described by several different wavefunctions. However, these wavefunctions are all of the same energy.
What is degeneracy?
Holly wants to approximate the energy of her atomic and molecular orbitals. This is what we call the set of mathematical functions to perform this calculation.
What is a basis set?
When Holly feels cold and starts shaking uncontrollably, pulling her limbs closer and farther away from her, this requires energy. On the other hand, when Holly is staying still with her limbs at a comfortable distance, no additional energy is required.
What is an equilibrium bond length?
