HIGH RESOLUTION INFRARED SPECTROSCOPY AND ANALYSIS OF METHYLISOCYANIDE BANDS IN THE 1370−1560cm−11370-1560 cm^{-1} REGION

Author Institution: Department of Chemistry, The Pennsylvania State University; Department of Physics, The Pennsylvania State University; Department of Chemistry, The Pennsylvania State University; Department of Chemistry, The Pennsylvania State UniversityThe region $1370-1560 cm^{-1}$ contains two fundamental bands, the strong perpendicular band of the doubly degenerate $\nu_{6}$(species E) and the parallel band of the totally symmetric $(A_{1})$ vibration $nu_{3}$. In addition, the $\nu_{7} + \nu_{8}$ and $\nu_{4} + 2\nu_{8}$ combination states also occur in this region. The two fundamentals interact strongly by a first order $J_{x,y}$,-Coriolis coupling while the E component of $\nu_{7} + \nu_{8}$ is in Fermi resonance with $\nu_{6}$, and the $A_{1}$ and $A_{2}$ components of $\nu_{7}+\nu_{8}$ are in Fermi resonance with the $nu_{3}$ fundamental. Also in evidence are an additional weaker anharmonic resonance of $\nu_{6}$ with the $\nu_{4} + 2\nu_{8}^{2}$ combination, as well as x,y - Coriolis-type and second-order rotational interactions which couple the various states. The interactions are incorporated into a $9 \times 9$ Hamiltonian matrix used for the upper states to adjust their spectroscopic constants yielding an overall standard deviation of the fit to all observed lined of $0.0015 cm^{-1}$. Spectroscopic parameters for all the states involved and for their interactions will be reported

Omezeni vlivu emisi toxickych plynu ze staji na zivotni prostredi

The final report presents suggested and verified measurement methodics of ammonia concentration in stables, described approach of the measuring apparatus setting up and construction of the sensing unit calibration curve. Further, there was presented list of so far suggested and verified technologies for ammonia emissions reduction originated in livestock husbandry, storage and handling with excrements and manure. The results of the project realisation have enabled to arrange the Implementation Plan for the ACETO Protocol requirements introduction. In addition there was worked-up the national Plan of the NH_3 emissions reductionAvailable from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi

ROVIBRATIONAL ANALYSIS OF THE CH STRETCHING OF METHYL ISOCYANIDE

Author Institution: Department of Chemistry, Penn State University; Department of Physics, Penn state UniversityThe symmetric stretching of the methyl group ($v_{1}$) of $CH_{3}NC$ has been recorded using a Fourier Transform Spectrometer with an unapodized resolution of $0.004 cm^{-1}$. The rotational structure has been revealed for the first time, and the molecular constants have been obtained. Over 400 spectral lines have been assigned to the P- and R-transitions of this parallel band with $K = 0$ to $K=6$ and $J = 40$. The rotational structure of the $v_{1}$ is quite different from a typical parallel band (e.g., $v_{4}$ of $CH_{3}NC$ because of the small $\Delta$(B) and large $\Delta$(A-B) values, giving rise to an intermingling of spectral lines belonging to different J-multiplets. In addition, all of the K-subbands have been observed to he strongly perturbed. The structure analysis, spectral assignment, and perturbation origin will be discussed in this presentation."
