Denationalisation and Its Discontents

Citizenship Revocation in the 21st Century: Legal, Political and Moral Implications

By: Christian Prener

This book offers a timely, critical and multifaceted examination of the Western revival of citizenship revocation in the 21st century and the practice’s justification within international human rights law, moral philosophy and political theory.

Oxidation Numbers and Oxidation States

By: Christian Klixbüll Jorgensen

The correlation of spectroscopic and chemical investigations in recent years has been highly beneficial of many reasons. Around 1950, no valid explanation was available of the colours of compounds of the five tran sition groups. Later, it was possible to identify the excited levels with those expected for an electron configuration with adefinite number of electrons in the partly filled shell. I t is not generally recognized that this is equivalent to determining spectroscopic oxidation states related to the preponderant electron configuration and not to estimates of the fractional atomic charges. This brings in an entirely different type of description than the formal oxidation numbers used for characterizing compounds and reaction schemes. However, it must be realized that collectively oxidized ligands, formation of cluster-complexes and catenation may prevent the oxidation state from being well-defined. The writer would like to express his gratitude to many, but first of all to DR. CLAUS SCHÄFFER, University of Copenhagen, who is the most efficient group-theoretical engineer known to the writer; his comments and discussions have been highly valuable. The writer's colleague, Pro fessor FAUSTO CALDERAZZO (now going to the University of Pisa) has been most helpful in metallo-organic questions. Thanks are also due to Professors E. RANcKE-MADsEN and K. A. JENSEN for correspondence and conversations about formal oxidation numbers.

Lasers and Excited States of Rare Earths

By: Renata Reisfeld,Christian K. Jorgensen

The possibility of stimulated light emission was discussed by Einstein in 1917, eight years before the quantum-mechanical description of energy levels of many-electron systems. Though it is imperative to use samples having optical properties greatly different from the stan dard continuous spectrum of opaque objects ("black body" radia tion) it is not always necessary to restrict the study to monatomic entities. Thus, spectral lines can be obtained (in absorption and in emission) from lanthanide compounds, containing from one to thir teen 4f electrons going from trivalent cerium to ytterbium, that are nearly as sharp as the ones from gaseous atoms. However, the presence of adjacent atoms modifies the simple picture of an isolated electron configuration, and in particular, it is possible to pump excited levels efficiently by energy transfer from species with intense absorption bands, such as the inter-shell transitions of other lanthanides and of thallium(I), lead(II) and bismuth(III) or the electron transfer bands of the uranyl ion or other complexes. On the other hand, it is possible to diminuish the mUlti-phonon relaxation (competing with sharp line luminescence) by selecting vitreous or crystalline materials with low phonon energies. Obviously, one cannot circumvent the conservation of energy by lasers, but they may have unprecedented consequences for the future by allowing nuclear fusion of light elements, effects of non-linear optics and time-resolved spectroscopy, besides the more conventional applications of coherent light beams with negligible angular extension.

The Pathway of Roses

The Divine Road to Supreme Freedom

By: Christian D. Larson

A classic of Christian mysticism, Larson's book describes the path to creating the life of prosperity and healing that you truly desire through becoming congruent with the divine essence within. The author explains that God's Will is never to produce suffering. Rather than becoming a passive recipient of fate, Divine Will is for every woman to enjoy the beauty, the power, the grace, and the opulence of the Creator's endless outpouring of love, support, prosperity, and healing. Transcribed from male-dominant language to wording more inclusive of the feminine voice.
