“…Intensities are primarily those of Pearse and Gaydon [187]. Duffendack and Pox [58] list a band at 4209.0 A as previously given, but this band is not further identified. Data from Johnson and Asimdi [121], Schmid and Gero [224], and Herzberg [97].…”

“…Herzberg and Hugo [101] The band system bearing his name was first observed by Cameron [39] in an uncondensed discharge in neon with a trace of CO ; the following year it was seen in absorption by Hopfield and Birge [104]. Johnson [119] Herman [94] The most precise measurements of the a-X system have recently been made by Pao [201] who has given the rotational structure of the 0-0, Later this system was observed by Duffendack and Fox [57, 58] who concluded that the group of bands labeled by Johnson [119] as the y' = 4 progression constituted the v'= 0 progression of a new system called 3 A.…”

As the PET was exposed in the O 2 plasma flow, light emitted from the PET surface was monitored. In the diagnosis measurement, several emission peaks assigned to the H ␣ atomic line at 652 nm, H ␤ at 486 nm, OH ( 2 ⌺→ 2 ⌸) transition near 244 -343 nm and CO (b 3 ⌺→a 3 ⌺) near 283-370 nm were observed and measured at various discharge times. These results indicated that after the plasma etching, the PET sample was decomposed by the oxygen plasma reaction, and then, hydrogen abstraction and carbon oxidation processes. We also observed the time profile of oxygen atom, as the atom-emission intensity at 777 nm was monitored. As H ␤ atomic and OH molecule lines appeared in the presence of PET, the O atom intensity was significantly reduced. In the surface analysis on Fourier transform infrared and x-ray photoelectron spectroscopy measurements, it was found that for the PET surface treated by O 2 plasma containing excited atomic oxygen species, ester bands were broken and carbonization formed on the PET surface.

Sommaire. 2014 Un postulat a été posé pour définir la valeur de l'énergie de répulsion s'exerçant entre les deux ions d'une molécule. Si une molecule A2 comprend 2n électrons de liaison, nons pouvons représenter celle molécule par le symbole : (A+nA+n)-2n. Soient : S2nm, Sna les sommes des 2n premiers potentiels d'ionisation de la molécule et des n premiers potentiels d'ionisation de l'atome; Im et In les potentiels d'ionisation expérimentaux de la molécule et de l'atome. Notre postulat s'exprime par la relation : D'où il résulte que le travail nécessaire pour dissocier la molécule normale en deux atomes normaux est : Ce postulat fut étendu à certanies molécules APp. Il conduit alors à l'équation générale : Le postulat proposé est expérimentalement vérifié pour les molécules H2, O2, N2, C2, S2, Cl2, HCl, CH4, SO2, H2O, H2S, CH3 2014 CH3, CH2 = CH2, CH = CH .. etc. Au cours du travail sont développées des considérations sur les radicaux OH, SO, CH3, CN... etc, ainsi que sur leur énergie d'association qui est donnée par la relation : Ia étant le potentiel d'ionisation de l'atome possédant dans le radical un électron de valence libre (O, S, C..., etc.). Nous examinons dans ce mémoire les vérifications expérimentales portant sur H2, N2, CO, CO2 (1). ha définition du potentiel d'ionisation d9un atome ne comporte aucune imprécision : c'est le travail nécessaire pour éloigner jusqu'à l'infini le moins lié des électrons. Mais, dans le cas d'une molécule, il convient de préciser davantage et de considérer l'état énergétique de l'ion obtenu. En on peut supposer que : j. Le travail considéré, uniquement électronique, correspond au départ de l'électron, laiis que soit changée la configuration moléculaire. La distance des deux noyaux dans fioii obtenu est la même que dans la molécule primitive (r,,). Si cette distance n'est pas celle de position d'équilibre (énergie minimum) des deux noyaux de l'ion dernier sera dans un état d'activation : 1,">.
