WebThe characteristic rotational temperatures 0rot for H2, HD, and D2 are 84.8, 63.8, and 42.6°K, respectively. The symmetry of H2 and D2 require that for optical transitions, AJ = … The characteristic rotational temperature (θR or θrot) is commonly used in statistical thermodynamics to simplify the expression of the rotational partition function and the rotational contribution to molecular thermodynamic properties. It has units of temperature and is defined as where is the rotational constant, I is a molecular moment of inertia, h is the Planck constant, c is the speed of light, ħ = h/2π is the reduced Planck constant and kB is the Boltzmann constant.

WebJul 8, 2024 · Mars' axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun. This is another similarity with Earth, which has an axial tilt of 23.4 degrees. Like Earth, Mars has distinct seasons, but they last longer than seasons here on Earth since Mars takes longer to orbit the Sun (because it's farther away). c# date time format 24 hour
