Transition Formula

The rotational Raman spectrum of gaseous NO was photographed with a spectral resolution of ~0.3 cm−1. In longer exposures the rotational structure of the electronic transition, [Formula: see text], was also observed. It consists of O, P, Q, R, and S branches and has an intensity distribution in accordance with theory.

The Raman spectrum of CH3–CD3 at 1 atm pressure was photographed with a spectral resolution of ~0.3 cm−1. The nondegenerate ν1 and ν3 and the doubly degenerate ν7 and ν11 fundamentals were observed. Analyses of the rotational structure of the ν3 and ν7 bands gave the rotational constants, B0 = 0.549 1 ± 0.000 3 cm−1 and A0 = 1.7809 ± 0.0016 cm−1, respectively. These are consistent with rotational constants previously obtained for C2H6 and C2D6.

First Time

The pure rotational Raman spectrum of nitric oxide has been recorded for the first time under high resolution. Analysis of the S-branch transitions yields values of 1.69614 cm−1 and 5.46 × 10−6 cm−1 for the rotational constants B0 and D0, respectively. A series of R-branch lines is observed and is shown to arise from transitions between levels in the 2Π3/2 substate. Some weaker R-branch lines arising from the 2Π1/2 state are also observed. A very weak feature approximately 120 cm−1 from the exciting line is interpreted as the 2Π3/2–2Π1/2 transition.

Polarization Measurements

The low temperature laser excited Raman spectrum of the compound thulium gallium garnet reveals the presence of an electronic transition of the thulium ion. The tensor associated with this transition can contain some asymmetry. Polarization measurements show, however, that the amount of asymmetry is too small to be detectable.

The F–X band system of Cu65Cl35 extending from 3700 to 4200 Å has been photographed in emission under high resolution. Rotational analysis of the (3,0), (2,0), (1,0), (0,0), (0,1), and (0,2) bands of the system has been made. The electronic transition involved is found to be 1Π–1Σ. The Λ-type doubling in the 1Π state is negligible. The principal molecular constants obtained are as follows (cm−1 units)[Formula: see text]

The A–X band system of CuCl has been photographed in emission under high resolution in the 2nd order of a 10.6 m concave grating spectrograph. Rotational structure in four bands, viz. (1,0), (0,0), (0,1), and (1,2) has been analysed. The present analysis confirms that in the A–X system the electronic transition involved is 1Π–1Σ where 1Σ is the ground state of the molecule. The Λ-type doubling in the 1Π state is found to be appreciable. The molecular constants for the excited A state of 63Cu35Cl are (with standard deviations in parentheses): Be = 0.168432(7) cm−1; αe = 0.001067(7); De = 0.1134(11) × 10−6; q = 0.000871(9); qD = 0.85(18) × 10−8; ν10 = 19 500.271(8); ν00 = 18 999.104(7); ν01 = 18 579.735(10); and ν12 = 18 574.745(11).

A unique method to design a high-throughput and high-resolution ultrathin Czerny–Turner (UTCT) spectrometer is proposed. This paper reveals an infrequent design process of spectrometers based on Coddington’s equations, which will lead us to develop a high-performance spectrometer from scratch. The spectrometer is composed of cylindrical elements except a planar grating. In the simulation design, spot radius is sub-pixel size, which means that almost all of the energy is collected by the detector. The spectral resolution is 0.4 nm at central wavelength and 0.75 nm at edge wavelength when the width of slit is chosen to be 25 μm and the groove density is 900 lines/mm.

AbstractUnlike the single grating Czerny–Turner configuration spectrometers, a super-high spectral resolution optical spectrometer with zero coma aberration is first experimentally demonstrated by using a compound integrated diffraction grating module consisting of 44 high dispersion sub-gratings and a two-dimensional backside-illuminated charge-coupled device array photodetector. The demonstrated super-high resolution spectrometer gives 0.005 nm (5 pm) spectral resolution in ultra-violet range and 0.01 nm spectral resolution in the visible range, as well as a uniform efficiency of diffraction in a broad 200 nm to 1000 nm wavelength region. Our new zero-off-axis spectrometer configuration has the unique merit that enables it to be used for a wide range of spectral sensing and measurement applications.
