Cabannes

Experimentally the Rayleigh ratio for benzene at 90° has been observed to equal about 1.58 X 10 m" under the conditions described in this example. By Eq. (10.6), r = (167t/3) so the value of R corresponding to this calculated turbidity is Rg = 5.41 X lO" m". The ratio between the observed value of Rq and that calculated in the example is called the Cabannes factor and equals about 2.9 in this case. 

Both quantum mechanical and classical theories of Raman scattering have been developed. The quantum mechanical treatment of Kramers and Heisenberg 5) preceded the classical theory of Cabannes and Rochard 6).

The expressions for scattered light intensity (and Rayleigh ratio) must be corrected by dividing by the appropriate Cabannes factor. Effectively this is equivalent to replacing the optical constant K as defined in Eq. (24) by Kf and by 2 Kfj for unpolarised and vertically polarised incident light respectively.

One of the most elegant LS studies on liquid mixtures is that of Sicotte and Rinfret17 and it will be instructive to summarise their approach solely with regard to that aspect which is concerned with molecular weight determination. Liquid 1 will be considered as solvent and liquid 2 (of ostensibly unknown molecular weight M2) as solute. The Rayleigh ratios implied are the isotropic ones, which are obtained for liquid 1 as well as for solutions (subscript 12) via the measured Cabannes factors [Eqs. (44) and (45)].

Evidently sensitive to that ever increasing cult of his own posterity, a year and a half before his death at the age of eighty-one, Duchamp consented to an extensive series of interviews. The interviewer, Cabanne, stated that the aged artist spoke to him,... 

This seemingly perverse textual application actually makes contextual sense. It is notorious that Duchamp fancied himself an initiate of Eros, EROS As he explained to Pierre Cabanne in 1966,... 

The first concretely iconographic sign of this new rotational interest, which Duchamp was in fact to pursue for decades, is encountered in a small oil sketch (33 x 12.5 cm) called the Coffee Mill (MD-61). According to Duchamp s posthumously published (1973), and typically bland, description of this miniscule mechanical operation, it shows the different facets of the coffee-grinding operation, and the handle on the top is seen simultaneously in several positions as it revolves. You can see the ground coffee in a heap under the cog-wheels of the central shaft, which turns in the direction of the arrow on top. He had already said much the same thing in 1966 to Pierre Cabanne ... 

As Duchamp also revealed to Cabanne in 1966, it was in his Sad Young Man in a Train that he first employed, in December 1911, the kind of anomalous procedure that was immediately to be reiterated in his famous (or infamous) painting of a certain Nude Descending a Staircase (MD-64). As we should suspect, if only on the basis of evidence for distinctive hermetic content now revealed to have been concealed in some contemporaneous paintings made by Duchamp, ce procidi probably was largely alchemical in character. 

Omitting the chess references, much the same thing was said two years later in the Cabanne interviews ...

In much later interviews with Pierre Cabanne, Duchamp recalled, not surprisingly, that Arensberg had a difficult character, poor man. He was a... 

Duchamp himself also praised, even invoked the awesome powers of the Spiritualist mediums who launched the modern branches of the Esoteric Tradition. As the artist eventually admitted to Pierre Cabanne, I do believe very strongly in the medium aspect of the artist... . There is the pole of the one who makes the work, and there is the pole of the one who looks at it. I give the latter as much importance as the one who makes it. On another occasion, Duchamp expanded much further upon the role of a modernist artists who overtly functions as a medium. Not only is the modem artist a spiritualistic medium, but also, says Duchamp, the spectator plays an essential role in the creative act. In order to explicate the creative acts symbioti-cally contributed to by both artist and viewer, Duchamp employs blatantly alchemical metaphors, a point typically overlooked in citations of this statement. As he stated, whereas the artist s imagery is refined from raw matter, the sensitive viewer undergoes a spiritual transmutation in the process of his esoteric act of decipherment and interpretation of a possibly impenetrable avant-garde work of art. 

Be that as it may, Duchamp told Cabanne in 1966 that, beginning with his nonsequitur snow shovel, The word ready-made thrust itself on...
