Use this app to calculate energy changes and transition wavelengths, frequencies and wavenumbers for
a one dimensional particle-in-a-box, a harmonic oscillator (vibration) and molecular rotation.
To get started, choose a system type and enter your system parameters (default values are provided).
The app will calculate the change in energy and transition wavelength, frequency and wavenumber given the
stated inital and final quantum numbers (also changeable).
PIB energies are calculated according to: En = (n2h2)/(8mL2)
Vibrational energies are calculated according to: Ev = hν(v + 1/2)
Rotational energies are calculated according to: EJ = ℏ2/(2μr2)[J(J+1)]
Wavelengths are calcuated according to: λ = hc/ΔE
Frequencies are calcuated according to: ν = ΔE/h
Wavenumbers are calcuated according to: wavenumber = ΔE/hc
