Notes Zeeman effect for two valence electron system In case of two valence electron system, there will be four individual magnetic moments associated with mechanical moment S_1*, S_2*, l_1* and l_2*. The vector sum of mechanical moment will ...
Notes Screening doublet law The "screening doublet law" in X-ray spectroscopy refers to a specific empirical relationship observed in the energies of characteristic X-ray emission lines from elements. This law describes how the …
Notes Spin and screening dublets in X rays spectrum In X-ray spectroscopy, particularly in the context of inner-shell transitions within atoms, spin and screening dublets refer to specific features in the spectrum that arise due to the spin-orbit …
Notes Fine structure of X ray levels The "fine structure" of X-ray levels refers to the detailed characteristics and properties associated with the energy levels of X-rays. Here are some key points regarding the fine structure of ...
Notes Franck Condon Principle The Franck-Condon principle is a fundamental concept in spectroscopy, particularly in electronic spectroscopy, that describes the transition between electronic states of molecules. Here's a breakdown …
Notes Rotational Fine Structure in electronic Vibration Transition Rotational fine structure refers to the splitting of vibrational energy levels into sub-levels due to the rotational motion of molecules. This phenomenon occurs in electronic-vibrational transitions …
Notes Isotopic effect in vibrational band of diatomic molecule Isotope Substitution: Isotopes of an element have different atomic masses but similar chemical properties. When an isotope (e.g., substituting hydrogen with deuterium) is substituted in a diatomic …
Notes Broadening of spectral line It has been observed that no strictly sharp spectral lines have been observed. It has a fixed width that depends on the reserving power of the optical instrument by which ...
