The cyano radical (CN) is a key molecule across many different factions of astronomy and chemistry. Accurate, empirical rovibronic energy levels with uncertainties are determined for 8 doublet states of CN using the Marvel{} (Measured Active Rotational-Vibrational Energy Levels) algorithm. otrans{} transitions were validated from osources{} different published sources to generate oenergy{} spin-rovibronic energy levels. The empirical energy levels obtained from the Marvel{} analysis are compared to current energy levels from the Mollist{} line list. The Mollist{} transition frequencies are updated with Marvel{} energy level data which brings the frequencies obtained through experimental data up to alert{77.3%} from the original 11.3%, with 92.6% of the transitions with intensities over 10$^{-23}$ cm/molecule at 1000 K now known from experimental data. At 2000 K, 100.0% of the partition function is recovered using only Marvel{} energy levels, while 98.2% is still recovered at 5000 K.
Zirconium oxide(ZrO) is an important astrophysical molecule that defines the S-star classification class for cool giant stars. Accurate, empirical rovibronic energy levels, with associated labels and uncertainties, are reported for 9 low-lying electr
The fractal properties of the total potential energy V as a function of time t are studied for a number of systems, including realistic models of proteins (PPT, BPTI and myoglobin). The fractal dimension of V(t), characterized by the exponent gamma,
A curious behavior of electron correlation energy is explored. Namely, the correlation energy is the energy that tends to drive the system toward that of the uniform electron gas. As such, the energy assumes its maximum value when a gradient of densi
We describe an experimental technique to measure the chemical potential, $mu$, in atomically thin layered materials with high sensitivity and in the static limit. We apply the technique to a high quality graphene monolayer to map out the evolution of
The experimental characterization of scattering resonances in low energy collisions has proven to be a stringent test for quantum chemistry calculations. Previous measurements on the NO-H$_2$ system at energies down to $10$ cm$^{-1}$ challenged the m
