Making: the invisible visible

In this book essay I argue that modern and contemporary works of art (i.e. paintings, photographs, films, and videos) really ought to retrieve something of their auratic-character, which turns the physical toward the metaphysical, the material toward the immaterial, the visible toward the invisible - making artworks, ‘things among things, something other than [a] thing’ (Theodor W. Adorno, Aesthetic Theory, 86). There is, perhaps, an aura to art or art is a medium or a conduit or a technology for rediscovering and reproducing aura, which makes it something other than a mere thing. Such works of art are constitutively enigmatic, a certain form of magic making: they (re-)distribute the visible and the invisible, they (re-)configure appearance and disappearance. Such works of art may become visual events, which begin an education in and through (dis-)appearances. To achieve this end, I detail Theodor W. Adorno’s and Walter Benjamin’s respective theories of (art’s) aura in the age of technological reproducibility, which I relate to Jacques Rancière’s more recent discussion of the ‘pensive image,’ and I focus my reading on a number of works by Susan Hiller (photographs), John Constable (paintings), Alfred Stieglitz (photographs), and Tacita Dean (photograph and 16mm film).

Amor intellectualis diaboli

An essay on love and liberty in the writings of Gillian Rose, Marquis de Sade, Max Horkheimer and Theodor W. Adorno, written in response to the following provocation: "Encore un effort. A banderole publicitaire carries the breathless descriptions of the new fashions for 1968, when anything goes and details place the accent on this or that part of the body and its adornment: a pair of shoes that come off in a struggle, for example, the heel of one snapped off; a striking checked shirt, with two buttons undone; a light-coloured trench coat (perfect for a May day); a blouson-style jacket that allows easy freedom of movement; place casual slacks worn with an ankle boot. Beauty is in the streets as fashion becomes democratic (or so say the houses of haute couture), while the philosopher of the boudoir extorts us once again to make an effort if we wish to be republicans. Here, to an assembled crowd of sensitive men and women, which petit-maitre or dangerous man of principles would suggest that the only moral system to reinforce political revolution is that of libertinage, the revenge of nature's course against the aberrations of society?"

Rotational spectra induced by vibrations

Mizushima and Venkateswarlu showed in 1953 that certain molecules have the property that excited vibrational states may possess rotational spectra even when the rotational spectrum of the ground vibrational state is forbidden by symmetry. We call such a spectrum a vibrationally induced rotational spectrum, and have made a systematic examination of the point groups which permit such behaviour. We also give formulae for the approximate line frequencies and intensities in these spectra, and discuss some of the problems involved in observing them. The spectra can only arise from degenerate vibrational states, and are of three possible types: i) symmetric top perpendicular spectra, shown by molecules belonging to the point groups Dnh, Dn and Cnh, where n is odd; (ii) symmetric top parallel spectra, shown by molecules belonging to Dnd and S2n, where n is even; and (iii) spherical top spectra, shown by molecules belonging to T or Td. Excited vibrational states of polar molecules of point groups Cnv or Cn, where n is odd, may also possess vibrationally induced perpendicular components of type (i), in addition to their ordinary parallel spectra. In addition to the above limitations on the point groups there are, in general, limitations on the symmetry species of the degenerate vibrational states.
