“…These studies show that the electronic ground state has been very well characterized by infrared-optical double resonance spectroscopy (Bares et al 1985), purely rotational spectroscopy (Törring & Herrmann 1989;Yamada et al 1990;Goto et al 1994), cavity-ring down spectroscopy (Kraus et al 2002), and by analysis of its fine structure splitting (Ito 1994) and of the photoelectron spectrum of its bound negative ion, AlO − (Desai et al 1997). Ab initio computations on the low-lying electronic states of AlO are also available (McDonald & Innes 1969;Yoshimine et al 1973;Dagdigian et al 1975;Lengsfield III et al 1982;Partridge et al 1983;Ito 1994;Launila & Jonsson 1994;Gilka et al 2008;Honjou 2010).…”

Using both standard and explicitly correlated ab initio methods in conjunction with several atomic basis sets, the ground state of AlO(X 2 Σ + ) and the two lowest electronic states of AlO + ( 1 Σ + and 3 Π) are investigated. Potential energy curves for these species are mapped, which are incorporated later to solve the nuclear motion problem. Benchmark computations on AlO(X 2 Σ + ) are used to determine the reliability of the theoretical methods and basis sets used for an accurate description of aluminum oxide compounds. The electronic ground state of AlO + is X 1 Σ + , followed by the low-lying 1 3 Π state. For both cationic electronic states, a set of spectroscopic parameters are recommended that may help in the identification of this ion in laboratory and astrophysical media. An accurate estimation of the adiabatic ionization energy of AlO, AIE = 9.70 eV, is also reported.

“…Because of its simplicity, ability to measure the absorption on an absolute scale, high sensitivity, and independence from pulse-to-pulse fluctuations of the laser (because of the analysis of time characteristics of the signal, rather than amplitudes), as well as its ready compatibility with small sample volumes or molecular beams, this technique has been widely used for various applications, spanning fundamental spectroscopy; [9][10][11][12][13][14][15][16][17][18] gas-phase circular dichroism measurements; 19 atmospheric photochemistry, 20,21 spectroscopy 22,23 and sensing; [24][25][26][27][28][29][30][31][32] environmental chemistry and pollution monitoring; [33][34][35][36] characterisation of temperatures, 37 electron densities 38 and chemical composition [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]…”

Continuous wave (cw) diode lasers are increasingly being used as light sources in the visible and near-IR regions of the spectrum for cavity ringdown spectroscopy (CRDS) and cavity enhanced absorption spectroscopy (CEAS); the latter technique is also widely known as integrated cavity output spectroscopy (ICOS). The very high sensitivities to weak absorptions that are possible with cw CRDS and CEAS, coupled with the quantitative nature of the absorption measurements, are enabling a rapidly expanding range of applications. We review the benefits and practical implementation of these techniques; methods of data analysis for extraction of quantitative absorption data; the sensitivities of cw CRDS and CEAS, and how they might be optimised; and applications of cw CRDS and CEAS in molecular spectroscopy, atmospheric chemistry, plasma and flame chemistry, analytical science, and medical diagnosis via breath analysis. The development of CRDS and CEAS techniques exploiting cw diode lasers and, very recently, high luminosity light-emitting diodes, has stimulated a wealth of highsensitivity measurements. Highlights include quantitative measurement of various ultra-trace gases such as: NO 3 , NO 2 and ethene in ambient air samples; CO 2 isotopologues, ethane and other organic compounds in human breath samples; and excited electronic states of N 2 and O 2 in plasmas and discharges. Exciting developments include wavelength extension into the mid-IR and UV regions, and use of novel locked-cavity techniques to increase data acquisition rates and sensitivities.

Indications of aluminium monoxide in atmospheres of exoplanets are being reported. Studies using high-resolution spectroscopy should allow a strong detection but require high accuracy laboratory data. A (measured active rotational-vibrational energy levels) analysis is performed for the available spectroscopic data on 27 Al 16 O: 22 473 validated transitions are used to determine 6 485 distinct energy levels. These empirical energy levels are used to provide an improved, spectroscopically accurate version of the ExoMol ATP line list for 27 Al 16 O; at the same time the accuracy of the line lists for the isotopically-substituted species 26 Al 16 O, 27 Al 17 O and 27 Al 18 O are improved by correcting levels in line with the corrections used for 27 Al 16 O. These line lists are available from the ExoMol database at www.exomol.com.
