“…X-ray absorption spectroscopy has been a particularly efficient structural probe for site-specific investigations in molecules, carrying priceless information on the local electronic structure and the neighboring coordination environment. A plethora of photoabsorption experiments on molecular targets have been performed at large scale synchrotron facilities (for an extensive review see reference [1]). Advances in free electron laser technology [2][3][4] made soft x-ray (SXR) pulses of high brightness and ultrashort duration available, allowing for studies on photo-induced molecular dynamics [5,6].…”

We report oxygen K-shell photoabsorption measurements in CO2 plasmas, using a table-top laser produced plasma soft x-ray (SXR) and extreme ultraviolet source. Significant differences are observed between the photoabsorption spectra of the neutral CO2 molecule and photoionized CO2 plasmas, as new spectral features emerge in the case of the latter. These features are attributed to photoexcitation in O, O+, O2+ species identified with the aid of calculations performed with the Cowan suite of atomic structure codes. Such signatures of atomic ions in the photoionized plasma point to the fragmentation of the parent molecule upon absorption of an SXR photon.

These were of great help during the revision of particular chapters of this thesis.I kindly appreciate the support and patience of Post-Graduate Comission of IF USP and it is my greatest pleasure to thank Eber de Patto Lima personally.Special gratitude goes to Nelson Yokomizo, the former member of "Quanta" group and Thais Silva, Doctorate student of IAG. My family and friends, who had been helping me throughout all these years of work deserve special thanks. Thank you. i ii ResumoConsideramos as características da radiação síncrotron (RS) noâmbito da teoria quântica. Para simplificar a descrição teórica do processo de radiação restringimosà consideração da emissão deúnico fóton. Para transições quânticas arbitrárias, as distribuições espectrais e angulares da potência da RS são dadas de forma analítica exata. Tratamos separadamente partículas escalares (bósons) e com spin /2 (elétrons). Atenção especialé dadaàs transições particulares, a saber, as transições ao primeiro estado excitado e estado fundamental.É mostrado que os componentes de polarização linear da radiação de elétron se trocam em relaçãoà orientação de spin quando o elétron passa para o estado fundamental.Este fato pode ser considerado como uma comprovação analítica para a presenca de π-componente da radiação quântica no plano de movimento.Analisamos minuciosamente a radiação emitida pela partícula fracamente excitada. Várias funções são introduzidas para descrever a evolução dos perfis de distribuições angulares para sistemas de dois e três níveis. Para transições quânticas do primeiro estado excitado ao estado fundamental a análise comparativa da radiação de bósons e elétronsé realizada, e isso ajuda a estimar a influência de spin e sua direção sobre as características da RS. A radiação de elétrons não polarizadosé considerada separadamente. Observando o comportamento dosângulos efetivos,é fácil perceber a inconsistência da conclusão clássica bem conhecida sobre a concentração de radiação ultra-relativista total no plano do movimento.Mostramos que osângulos efetivos da radiação quântica tendem aos valores finitos e não desaparecem na região ultrarelativista.Uma revisão breve da teoria clássica inclui a introdução do conceito novo, istoé a n-parte do espectro.A fim de encontrar um análogo clás...
