High-Resolution Survey of the Visible Spectrum of NiF by Fourier Transform Spectroscopy

High-Resolution Fourier Transform Spectroscopy of Three Near-Infrared Transitions of NiF

“…The combination of microwave and optical FTS data in the fits improved the accuracy of the parameters of the electronic states studied in Ref. (5). As a consequence, any transition involving one of the five low-lying states can now be studied easily.…”

“…The spectra of NiF were recorded in emission with a Bruker IFS 120 HR Fourier transform spectrometer (5). A CaF 2 beamsplitter and a silicon photodiode detector were used for a wide survey between 9500 and 13 000 cm −1 at a resolution of 0.03 cm −1 .…”

“…Molecular beam experiments were also performed, and they led to the identification of new excited electronic states and the observation of the vibrational structure for numerous transitions (2)(3)(4). A highresolution survey of the visible spectrum of NiF has also been recorded by Fourier transform spectroscopy (FTS) (5), leading to the reanalysis of numerous transitions studied previously (references to the many papers published on NiF before 1997 are listed in Ref. (5)).…”

Ab initio configuration-interaction study of the ground and low-lying electronic states of NiI

“…Transition-metal monohalides are important model systems for understanding the role of the d electrons in chemical bonding. 12 Knowledge of electronic structure of the ground and the excited states for NiF [13][14][15][16][17][18][19][20][21][22] and NiCl, [23][24][25][26][27][28][29][30] has been obtained through years of hard work of many workers, however, for the latter two nickel monohalides, namely, NiBr and NiI, only limited spectroscopic information is available. Recently Leung et al 31 using high-resolution laser spectroscopy, identified unambiguously the ground and three lowlying electronic states for NiBr.…”
