Vibrational Distribution

Emission from the HF product of the reaction F + N2H2 has been measured in an arrested-relaxation infrared chemiluminescence experiment. The vibrational distribution is inverted, peaking in HF(ν′ = 2). This energy partitioning indicates that the reaction occurs without the formation of a long-lived intermediate species. The detailed shape of the primary energy distribution could not be determined due to severe difficulties in the production of N2H2.

Work Production

The importance of a proximal-to-distal (P-D) sequential motion in baseball pitching is generally accepted; however, the mechanisms behind this sequential motion and motor control theories that explain which factor transfers mechanical energy between the trunk and arm segments are not completely understood. This study aimed to identify the energy distribution mechanisms among the segments and determine the effect of the P-D sequence on the mechanical efficiency of the throwing movement, focusing on the time-varying motor control. The throwing motions of 16 male collegiate baseball pitchers were measured by a motion capture system. An induced power analysis was used to decompose the system mechanical energy into its muscular and interactive torque-dependent components. The results showed that the P-D sequential energy flow during the movement was mainly attributed to three different joint controls of the energy-generation and muscular torque- and centrifugal force-induced energy-transfer. The trunk muscular torques provided the primary energy sources of the system mechanical energy, and the shoulder and elbow joints played the roles of the energy-transfer effect. The mechanical energy expenditure on the throwing hand and ball accounted for 72.7% of the total muscle work generated by the trunk and arm joints (329.2 J). In conclusion, the P-D sequence of the throwing motion is an effective way to utilize the proximal joints as the energy source and reduce muscular work production of the distal joints. This movement control assists in efficient throwing, and is consistent with the theory of the leading joint hypothesis.

Vibrational Energy Distribution

Vibrational energy distribution of IR MP-excited CF2Cl2 is studied when pumping molecules through ν1 and ν8 modes. In both cases the intermolecular distribution is found to be in a state of nonequilibrium consisting of ensembles of “hot” and “cold” molecules. The structure of the “cold” ensemble is different when ν1 and ν8 modes are pumped. Statistical intramolecular energy distribution caused by stochastization of vibrational motion is found for “hot” molecules. The estimated value of stochastization onset energy equals Eth ≤ 7800 cm−1.

Vibrational Energy Distribution

The reactions of Ba with CF3I dimers and CH3IAr complexes were studied applying the laser induced fluorescence (LIF) technique. It was found that the BaI produced from the dimers contains about 20 kcal/mole less vibrational energy than the BaI produced in the corresponding monomeric reaction. The CH3IAr on the other hand, yielded only a slightly colder vibrational distribution than the monomers.

Relative Kinetic

The vibrational distribution in the OH created by the reaction of O(1D2) atoms with NH3 has been recorded directly using low pressure infrared emission spectroscopy. The relative kinetic energy of the reagents is Boltzmann at 300 K. The OH product vibrational levels are populated statistically, indicating that the reaction probably involves a long-lived ONH3 intermediate. There is some evidence that this may not be the case at higher reagent translational energies.
