High-resolution spectroscopy used to observe hyperfme structure in the spectra of atoms or rotational stnicture in electronic spectra of gaseous molecules connnonly must contend with the widths of the spectral lines and how that compares with the separations between lines. Tln-ee contributions to the linewidth will be mentioned here tlie natural line width due to tlie finite lifetime of the excited state, collisional broadening of lines, and the Doppler effect.

The choice of phase of the sample is important. Generally, in high-resolution spectroscopy (see Section 3.3.1 for a discussion of resolution), the sample is in the gas phase at a pressure which is sufficiently low to avoid pressure broadening (see Section 2.3.3). In the liquid... 

When my previous book High Resolution Spectroscopy was published by Butterworths in 1982 1 had it in mind to make some of the subject matter contained in it more accessible to students at a later date. This is what 1 have tried to do in Modern Spectroscopy and 1 would like to express my appreciation to Butterworths for allowing me to use some textual material and, particularly, many of the figures from High Resolution Spectroscopy. New figures were very compefenfly drawn by Mr M. R. Barton. 

Alfhough 1 have nof included High Resolution Spectroscopy in fhe bibliography of any of fhe chapfers if is recommended as further reading on all topics.

The emission spectrum observed by high resolution spectroscopy for the A - X vibrational bands [4] has been very well reproduced theoretically for several low-lying vibrational quantum numbers and the spectrum for the A - A n vibrational bands has been theoretically derived for low vibrational quantum numbers to be subjected to further experimental analysis [8]. Related Franck-Condon factors for the latter and former transition bands [8] have also been derived and compared favourably with semi-empirical calculations [25] performed for the former transition bands. Pure rotational, vibrationm and rovibrational transitions appear to be the largest for the X ground state followed by those... 

Ultimately, however, one seeks abundances from high-resolution spectroscopy, and a full elemental abundance analysis. Data on a broad range of elemental abundances in open clusters have been limited until recently. Fortunately, this situation is beginning to change.

Abstract. The Milky Way harbours two disks that appear distinct concerning scale-heights, kinematics, and elemental abundance patterns. Recent years have seen a surge of studies of the elemental abundance trends in the disks using high resolution spectroscopy. Here I will review and discuss the currently available data. Special focus will also be put on how we define stars to be members of either disk, and how current models of galaxy formation favour that thick disks are formed from several accreted bodies. The ability for the stellar abundance trends to test such predictions are discussed. 

Recent surveys of metal-deficient stars have discovered a large number of carbon-rich objects, with a marked increase in their frequency at [Fe/H] < —2.5. In order to constrain the origin(s) of their carbon excesses, we have performed elemental abundance analyses for 40 objects selected from candidate metal-poor stars with strong CH G bands identified in the HK and Hamburg/ESO surveys. High-resolution spectroscopy has been obtained with AAT/UCLES and Subaru/HDS a portion of these studies have already been published [1—3]. 

The problem with molecular astronomy is knowing where to start and, more importantly, where to stop. The laboratory-based big brother of molecular astronomy is the field of high-resolution spectroscopy. The synergy between these two subjects... 

These methods, using well-defined band passes, are capable of a better internal precision than high-resolution spectroscopy (as well as being vastly quicker), but they give (in general) only one abundance parameter and they need high-resolution spectroscopy for calibration. 

A catalogue of stellar abundances based on high-resolution spectroscopy is described (along with references to earlier catalogues) by...
