Solutions of Schrodinger Equation And Thermodynamic Properties of Potassium Dimer Based On Formular Method

The study presents the thermodynamic properties of the XI Σ+g state of potassium (K2) dimer with molecular Deng-Fan potential. The bound state energy solution of the radial Schrodinger equation is obtained via the formula method. The partition function and other thermodynamic properties are evaluated. The numerical values of energy are found to be in agreement with results obtained from other methods in literature. The results further show that the partition function increases as temperature decreases, which implies a decrease in the probability of finding a particle in a state with quantum number, n.

FEMTOSECOND VIBRATIONAL DYNAMICS OF POTASSIUM DIMER

Combining the femtosecond pump & probe technique with isotope-selective detection, the dynamics of the [Formula: see text] state could be investigated. The three-photon-ionization (3PI) signal was recorded over a delay time range of 220 ps. A strong oscillation around the zero-of-time dephases within 10 ps. Fourier analysis of the spectrum yields a group of frequencies settled between 63 and 68 cm−1 which can be assigned to the energy spacings in the A state being excited by a 90-fs laser pulse. The corresponding vibrational periods could be estimated to lie between 499 and 520 fs.
