he vantage of engineers and experimentalists with applicatioThis text provides an introduction to the science that governs the interaction of light and matter (in the gas phase). It provides readers with the basic knowledge to exploit the light-matter interaction to develop quantitative tools for gacarotid-bruit 发表于 2025-3-27 13:49:26

Introduction,prima facie, the results of quantum mechanics (explaining quantum mechanics in detail would require another complete text, of which many are already available). That is, we accept that an atom or molecule may exist only in specific quantum states (characterized by quantum “numbers”), with each quant翻布寻找 发表于 2025-3-28 01:27:59
Bond Dissociation Energies, directly affect heats of formation and reaction. Dissociation energies thus also play key roles determining rates of reaction as a function of temperature. This chapter will give several examples of how spectroscopic information can reveal .. (of ground and excited electronic states).Ointment 发表于 2025-3-28 05:57:21
Polyatomic Molecular Spectra,lar vibrations and rotations cause changes in electric dipole moments that occur at resonant frequencies. At these frequencies, molecules can interact with radiation (via emission, absorption, or scattering). The difference is that polyatomic molecules have more rotational and vibrational modes, andCorroborate 发表于 2025-3-28 06:42:58
Effects of Nuclear Spin: Rotational Partition Function and Degeneracies,n Boltzmann statistics. Rotational angular momentum is, in fact, only one kind of angular momentum that must be considered when evaluating real molecules and their spectra. For example, electrons also have quantized angular momentum as they orbit nuclei (called . angular momentum, which we will discSoliloquy 发表于 2025-3-28 13:36:36
Rayleigh and Raman Spectra, explore scattering processes further is that while absorption requires that the molecule have energy-level spacings (for allowed transitions) corresponding to the energy of the interacting photon, scattering can occur with an incident photon of almost any energy. That is, for a molecule to absorb l
