This table of gf values for 265,587 atomic lines is selected from the line data used to calculate line-blanketed model atmospheres (Kurucz et al. 1974). The data are especially...

Detailed studies of the internal motions of dark clouds using spectral lines of many molecules require a laboratory frequency accuracy of the order of a few m/s. Based on our...

The calculations of the spectrum and oscillator strengths for the 4f^7^-(4f^6^5d+4f^6^6s) Eu III transitions. The calculations were performed with Cowan's RCN-RCG-RCE codes in...

The Keck telescope's High Resolution Spectrograph (HIRES) has previously provided evidence for a smaller fine-structure constant, {alpha}, compared to the current laboratory...

Multiple photoionization is investigated for the 2p shell in the iron atom. Study of the single photoionization with subsequent radiative and Auger cascade includes all levels...

Missing Stark widths for 37 spectral lines of strontium ions (17 SrV lines and 20 SrVI lines) have been calculated using a quantum-mechanical method. Twenty-three spectral lines...

A new silicon monoxide (^28^Si^16^O) line list covering infrared, visible and ultraviolet regions called SiOUVenIR is presented. This line list extends the infrared EBJT ExoMol...

Extensions have been made recently to the coronal approximation for the purpose of modelling line emission from carbon and oxygen in the lower solar atmosphere. The same...

HCO^+^ is one of the most abundant polyatomic ion in the Universe, also its presence in the planetary atmospheres and interstellar medium (ISM) makes it an interesting case to...

To predict line emission in the solar atmosphere requires models which are fundamentally different depending on whether the emission is from the chromosphere or the corona. At...

Large-scale calculations of atomic structures and radiative properties have been carried out for singly, doubly- and trebly ionized cerium. For this purpose, the purely...

The ion populations most frequently adopted for diagnostics in collisional plasmas are derived from the density independent, coronal approximation. In higher density, lower...

A new hot line list for ^14^NH_3_ is presented. The line list CoYuTe was constructed using an accurate, empirically refined potential energy surface and a CCSD(T)/aug-cc-pVQZ ab...

The GYT line list covering rotational, rovibrational and rovibronic transitions of the mercapto radical SH is presented. This work extends and replaces the SNaSH line list...

Accurate line lists are crucial for correctly modelling a variety of astrophysical phenomena, including stellar photospheres and the atmospheres of extra-solar planets. This set...

A rovibronic line list for the ground (X^3^{Sigma}^-^) and first excited (a^1^{Delta}) states of phosphinidene, 31PH, is computed. The line list is designed for studies of...

Line lists for magnesium oxide are computed and extensive comparisons are made with existing experimental spectra. The LiTY line lists cover all ro-vibration transitions within...

Accurate line lists for the carbon dimer, C_2_, are presented. These line lists cover rovibronic transitions between the eight lowest electronic states: X, A, B, B', a, b, c, d....

Comprehensive rotation-vibration line lists in the form of temperature-dependent super-lines are presented for the two main isotopologues of methyl chloride, ^12^CH_3_^35^Cl and...

A new line list for AlH is produced. The WYLLoT line list spans two electronic states X^1^{SIGMA}^1^ and A^1^{PI}. A diabatic model is used to model the shallow potential energy...
