Show Abstract
Atomic transition probabilities for about 1500 allowed spectral lines of the elements scandium and titanium through all stages of ionization have been critically evaluated and compiled. All available literature sources have been utilized. The data are presented in separable tables for each element and stage of ionization and are arranged according to multiplets and, when appropriate, also to transition arrays and increasing quantum numbers. For each line the transition probability for spontaneous emission, the absorption oscillator strength, and the line strength are given along with the spectroscopic designation, the wavelength, the statistical weights, and the energy levels (when available) of the upper and lower atomic states. In addition the estimated accuracy and the literature reference is indicated. In short introduction, which precede the tables for each spectrum, the main justifications for the choice of the adopted data and for the accuracy rating are discussed. A general introduction contains some more details on our evaluation procedure.

Show Abstract
The energy levels of the iron atom in all of its stages of ionization, as derived from the analyses of atomic spectra, have been compiled. In cases where only line classifications are given in the literature, level values have been derived. The percentages for the two leading components of the calculated eigenvectors of the levels are given where available. Ionization energies are also given.

Show Abstract
The molecular structural parameters, the vibrational fundamentals, the potential barrier height to internal rotation, and the standard enthalpy of formation for each of the six fluoroethanes in which at least one of the internally rotating groups is a symmetric top have been extensively studied and recommended values selected. Chemical thermodynamic properties of molecules in the ideal gas state at temperatures from 0 to 1500 K have been calculated with the rigid‐rotor harmonic‐oscillator approximation. The calculated values are in very good agreement with the existing third‐law entropies.

Show Abstract
The available molecular parameters, fundamental frequencies, and enthalpy of formation for eight bromo‐ and indomethanes have been critically evaluated and recommended values selected. This information has been utilized to calculate the ideal gas thermodynamic properties.
