چکیده

Published high-resolution rotation-vibration transitions of \spec{h212c16o}, the principal isotopologue methanal, are analyzed using MARVEL (Measured Active Rotation-Vibration Energy Levels) procedure. The literature results augmented by new, high-accuracy measurements pure rotational within ground, $\nu_3$, $\nu_4$, and $\nu_6$ vibrational states. Of \nbNonRedTr\ non-redundant processed, which come from \nbSr\ sources including present work, \nbValTr\ could be validated, providing \nbEl\ empirical energy levels \spec{h212c16o}\ with statistically well-defined uncertainties. All rotational-vibrational determined used to improve accuracy ExoMol's AYTY line list for hot formaldehyde. complete collated experimental transitions, determined, as well extended improved provided Supplementary Material.

1995 Atmospheric Trace Molecule Spectroscopy (ATMOS) linelist.

The Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment uses a Fourier-transform spectrometer on board the Space Shuttle to record infrared solar occultation spectra of the atmosphere at 0.01-cm(-1) resolution. The current version of the molecular spectroscopic database used for the analysis of the data obtained during three Space Shuttle missions between 1992 and 1994 is described. It i...

Rovibrational levels of HD.

The dissociation energies of all rotation-vibrational states of the molecular HD in the ground electronic state are calculated to a high accuracy by including nonadiabatic, relativistic alpha(2), and quantum electrodynamic alpha(3) effects, with approximate treatment of small higher order alpha(4), and finite nuclear size corrections. The obtained result for the ground molecular state of 36 405...

An Improved WAGNER-WHITIN Algorithm

We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...
