Table of coefficients for energy unit conversion between atomic unit (hartree), joule (J), electron volt (eV), cm-1, kJ/mol, and kcal/mol.
7 Δεκ 2023 · Divide joules by 1.6 × 10 –19 to get the equivalent energy in electronvolts. Converting between electronvolts and joules. Sometimes, units of MeV or GeV are used. These are given by: 1 MeV = 1 × 106 eV = 1.6 × 10–13 J. 1 GeV = 1 × 109 eV = 1.6 × 10–10 J.
Planck’s Equation E = hv. E stands for energy (in Joules), v stands for frequency [in reciprocal seconds – written s-1 or Hertz (Hz)- 1Hz = 1 s-1), h is Planck’s constant. Provided on your exam data sheet (6.626x10-34 J.s) This equation is said to define the relationship between energy and frequency in a black body.
