La science est un modèle qui mime dans l'abstrait le comportement de la nature. Créations du chercheur, les théories pour un fait donné peuvent être multiples et chacune valide. La science a des lois, la nature n'en a pas. L'ordre de la nature,

Spectra, obtained in visible and near infrared spectral regions, contain much information whose interest depends on the context. For instance, in a discrimination context, the only information of interest is the one, concerning the differences betwee

In the frame of the French EUV program PREUVE, different studies are made on different key aspects of EUV lithography. Aspheric optics are fabricated for the exposure test bench as well as mask blanks. All these objects require Mo/Si multilayer coati

When pyridine is para substituted to the nitrogen atom, the intensity of the long wavelength electronic transition is strongly decreased compared to the ortho and meta derivatives. N belonging to the ring, plays the part of a donating center when a s

The Interaction Vector Model (IVM) is used to understand the behaviour of the intensity of the secondary transition of chloro derivatives of the benzene chromophore, extending the work to some fluoro derivatives. These latter molecules show a surpris

The Interaction Vector Model (IVM) is used to study the intensity of the near UV transition of phenolates. Thirteen phenolates have been studied using the phenolate anion as a reference. The modulus of the-O−⇔-CH3 ortho interaction vector has bee

An experimental study of the diffraction of X rays in the keV region by a lamellar multilayer amplitude grating is described. This optics is obtained by periodic etching of an interferential multilayer mirror down to the substrate. The advantages pro

The secondary transition of the benzene molecule lies towards 250-260 nm. It is electronically forbidden because of the D6h symmetry of the molecule. The intensity of the transition is low (∊max = 220; medium : cyclohexane) and very sensitive to in

The interaction vector model1-3 (IVM) has been used to calculate on a very simple basis, and a good accuracy, the intensity of the secondary transition of the benzene chromophore of more than 80 molecules. In this paper we shall study the phthalic an
