The infrared spectra of the metaborate monomer and trimer
ions in NaC1, KC1, and KBr were studied. These spectra contain
bands due to the trimer in solid solution, in a second phase of the appropriate
potassium or sodium salt, and perhaps on adjacent lattice
sites. Furthermore, complex equilibria exist between...
The investigation
of impurity effects on the properties of alkali
halide crystals has often been difficult because of the variation of procedures used in various experiments.
The purpose of this work is to
develop a self consistent method of measuring the IV dipole polarization properties of single crystals while eliminating...
The hydroxide ion as a substitutional defect in KC1 can be photo-dissociated
at liquid nitrogen temperature by ultraviolet light. The
photochemistry of this system was investigated by EPR and optical absorption
methods. Theoretical calculations were also performed in an
investigation of the KC1:OH system.
The bleaching behavior of photochemically colored...
When trace quantities of an alkali element are added to a flame,
its optical and electrical properties change significantly. Addition of
alkali seed to both premixed and diffusion flames has been used in the
development of two new techniques, one for flame temperature measurement
and the other for enhanced mixing....
Novel ternary graphite intercalation compounds (GICs) of alkali metal cations
and a wide variety of amines have been synthesized by one-pot chemical syntheses.
Alkali metals studied includes Li, Na and K. The families of amines employed are nalkylamines,
branched alkylamines, and different structural isomers of diamines and
polyamines. Intragallery structures...
