Atomic and Molecular Spectroscopy: Basic Aspects and Practical Applications

Atomic and Molecular Spectroscopy is a wide-ranging review om modern spectroscopic techniques such as X-ray, photoelectron, optical and laser spectroscopy, and radiofrequency and microwave techniques. On the fundamental side it focuses on physical principles and the impact on spectroscopy on our understanding of the building blocks or matter, while in the area of applications particular attentionis given to those in chemical analysis, photochemistry, surface characterisation, environmental and medical diagnostics, remote sensing and astrophyscis. Important references are updated till He has extensive research experience in radiofrequency, optical and laser spectroscopy, and in the use of lasers in combustion diagnostics, environmental monitoring, and medical diagnostics and treatment, and is thus in good position to cover the vast scope of the book. Sune Svanberg has coauthored almost papers and trained a large number or undergraduates and graduates in basic and applied atomic and molecular spectroscopy. He served extensively in international organisations and scientific advisory committees. He is a member of five academies and holds three honorary doctor degrees.

Unlike atoms in which the quantization of energy results only from the interaction of the electrons with the nucleus and with other electrons, the quantization of molecular energy levels and the resulting absorption or emission of radiation involving these energy levels encompasses several mechanisms. In theory there is no clear separation of the different mechanisms, but in practice their differences in magnitude allow their characterization to be examined independently. Using the diatomic molecule as a model, each category of energy will be examined. In the gas phase, molecules are relatively far apart compared to their size and are free to undergo rotation around their axes. If a diatomic molecule is assumed to be rigid i. Molecular rotational spectra originate when a molecule undergoes a transition from one rotational level to another, subject to quantum mechanical selection rules. Selection rules are stated in terms of the allowed changes in the quantum numbers that characterize the energy states.

Spectroscopy

Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory LIGO. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics , chemistry , and astronomy , allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances. Important applications arise from biomedical spectroscopy in the areas of tissue analysis and medical imaging. Spectroscopy and spectrography are terms used to refer to the measurement of radiation intensity as a function of wavelength and are often used to describe experimental spectroscopic methods.

Бринкерхофф не знал, что на это ответить. - Ты утверждаешь, что Стратмор намеренно запустил в ТРАНСТЕКСТ вирус. - Нет! - отрезала.  - Не думаю, что он знал, что имеет дело с вирусом. Я думаю, он был введен в заблуждение. Бринкерхофф молчал.

Бело-красно-синие волосы, майка, серьга с черепом в ухе. Что. - Больше. Панк да и. Панк да и. Беккер принадлежал к миру людей, носивших университетские свитера и консервативные стрижки, - он просто не мог представить себе образ, который нарисовала Росио.

Это был высокий мужчина крепкого сложения с густыми светлыми волосами и глубокой ямкой на подбородке.

 Вы себя хорошо чувствуете? - спросил он, пятясь к двери. - Нормально, - высокомерно бросила.  - А тебе здесь делать нечего.

 Совершенно. Будет очень глупо, если вы этого не сделаете. На этот раз Стратмор позволил себе расхохотаться во весь голос.

Он редко встречался со Стратмором с глазу на глаз, но когда такое случалось, это можно было сравнить с битвой титанов.
