THE R SPECTRA OF ATOMS AND MOLECULES

The con-cept of R spec-tra of atoms and mo-le-cu-les is de-ve-lo-ped to gi-ve spec-tral pro-fi-les in in-di-vi-du-al exam-ples. The con-cept is ba-sed on ab-sorp-ti-on the-ory with con-ser-va-ti-on of li-ne-ar mo-men-tum cor-rectly con-si-de-red for the first ti-me. The-se con-si-de-ra-ti-ons ex-tend the Ein-ste-in energy equ-a-ti-on and rest energy con-cept to ge-ne-ral re-la-ti-vity, the rest mass con-cept of spe-ci-al re-la-ti-vity be-co-mes the co-va-ri-ant mass of ge-ne-ral re-la-ti-vity, de-fi-ned in terms of the R fac-tor with units of in-ver-se me-tres squ-a-red. Each ato-mic or mo-le-cu-lar tran-si-ti-on has its own R spec-trum or pat-tern.
