Kinetic Energy Release and Metastable Transitions
نویسنده
چکیده
The decompositions of doubly-charged ions given by a number of C3 —C8 aliphatic and alicyclic hydrocarbons have been investigated in a double-focusing mass spectrometer. Many processes were found in which high kinetic energy CH3+ and C2H3+ ions are formed. Doubly-charged ions fragment by more than one route and in many cases, high kinetic energy fragment ions are formed in at least two different ways. Metastable transitions common to several compounds were observed, the inten sities rising as the degree of unsaturation increased.

Kinetic Energy Release in Metastable Transitions. I
A method is described for detecting metastable transitions which take place with the release of kinetic energy in the field-free region between the source and electrostatic analyser of a doublefocusing mass spectrometer, and a procedure is given for evaluating the kinetic energy release. Values are given for a number of transitions and are in agreement with those obtained by other methods where...
متن کاملComputation of Metastable Phases in Tungsten-carbon System
Metastable phase equilibria in the W-C system are presented in the vicinity of the metastable reactions involving W2C, WC1-x, and WC. Metastable phase boundaries were obtained by reproducing the stable boundaries using optimized Gibbs energy formulations and extrapolating them into regions of metastability. Four metastable reactions were obtained: a metastable congruent melting reaction of WC a...
متن کاملOn the robustness of the ammonia thermometer
Ammonia inversion lines are often used as probes of the physical conditions in the dense ISM. The excitation temperature between the first two para metastable (rotational) levels is an excellent probe of the gas kinetic temperature. However, the calibration of this ammonia thermometer depends on the accuracy of the collisional rates with H2. Here we present new collisional rates for ortho-NH3 a...
متن کاملMetastable anions of dinitrobenzene: resonances for electron attachment and kinetic energy release.
Attachment of free, low-energy electrons to dinitrobenzene (DNB) in the gas phase leads to DNB(-) as well as several fragment anions. DNB(-), (DNB-H)(-), (DNB-NO)(-), (DNB-2NO)(-), and (DNB-NO(2))(-) are found to undergo metastable (unimolecular) dissociation. A rich pattern of resonances in the yield of these metastable reactions versus electron energy is observed; some resonances are highly i...
متن کاملApplication of guar gum in electrospun nanofibers as mebendazole drug release controller: a kinetic study and thermodynamics analysis
The current study aimed at in vitro investigating the kinetic study and thermodynamic analysis of mebendazole drug released from electrospun cellulose nanofiber in which guar gum is used as a release controller. The nanofibers were fabricated by electrospinning technique. The fibers were boosted by different controller guar gum 10 at 50, 250, and 500 ppm concentrations. The drug releas...
