Wavefunction Collapse Broadens Molecular Spectrum

Spectral lines in the optical spectra of atoms, molecules, and other quantum systems are characterized by a range frequencies ω or wavelengths λ=2πc/ω, where c is speed light. Such frequency wavelength called width spectral (linewidth). It influenced many specific factors. Thermal motion molecules results broadening as result Doppler effect (thermal broadening) their collisions (pressure broadening). The electric fields neighboring lead to Stark broadening. linewidth be considered here so-called parametric (PB) spectrum. PB can fundamental type electronic vibrational–rotational (rovibronic) transitions molecule, which direct manifestation basic concept collapse wavefunction that postulated Copenhagen interpretation mechanics. Thus, appears not only valid but also useful for predicting physically observable phenomena.
