where r is the distance between covalently bonded atoms , a is the corresponding equilibrium distance, and ka is the spring constant. The equilibrium distance between atoms can be obtained from X-ray diffraction experiments or using ab initio quantum calculations. The spring constant can be determined using the results of infrared adsorption and Raman spectroscopy. The frequency of bond length ...

to get a mole of a gas, it is necessary to calculate the intermolecular interaction. theseintermolecular interactions can be depicted by drawing the potential energy of a pair molecule inrelation to the distance. the intermolecular potential energy surface in the mixtures of ch4-h2cogases from ab initio calculations has been explored. in ab initio calculations the basis setsuperposition error (...

In this paper, we shall argue that games, being textual systems, can be understood semiotically signs, or units, are being constantly renegotiated within the game due to their ergodicity. However, the mythologies outside of them remain, leading to a potential discrepancy between what is and what is understood. An understanding of player mythologies can, on one hand, help us formulate a better s...

We develop some of the finer details of the location of the zeros of the weight two Eisenstein series. These zeros are the same as the zeros of the derivative of the Ramanujan delta function.
