Studies of vacuum ultraviolet absorption spectra of simple gases
<p>The spectra of ethylene and deuterated ethylene molecules have been photographed in the first order of a 21-foot vacuum ultraviolet spectrograph. The background continuum was provided by a xenon discharge lamp excited by a 2450 Mc/sec microwave diathermy unit. The exposure time varied from 30 …

Ultraviolet and visible absorption spectra of potassium and potassium-xenon mixtures
The visible absorption spectrum of the potassium dimer has been studied using a new type of optical cell designed specifically for the alkali vapors or alkali-rare gas mixtures. Particular emphasis has been placed on examining the diffuse K2 bands lying at 722 nm, 575 nm, 478 nm and 402 nm. …

Near infrared transient absorption spectra of photolyzed myoglobin at low temperatures
"We have measured the transient absorption spectrum of photolyzed sperm whale carboxymyoglobin as a function of temperature and time after photolysis. Our measurements extend from 60K to 220K and from three microseconds to thirty seconds. We see an absorption band near 758 nm which is known as band …

The electronic absorption spectra of di- and tri-arylmethane dyes containing fluorine
… to a dimethylamino- group. The observed visible spectra of the dyes have been correlated with structural features. Apparent inconsistencies in the response of Crystal Violet to the introduction of substituents have been interpreted in terms of a possible loss of degeneracy of the NBMO pair in the …

Electronic absorption spectra of basic dyes containing terminal diethylamino and morpholino groups
… Green have been synthesised and their visible absorption spectra have been correlated with structural features. The spectral data for the parent dyes have been compared with those for Malachite Green and the differences have been interpreted in terms of the relative basicity of the terminal …
