This review, published annually, provides an overview of advances in the field of Raman spectroscopy as found in papers published in the preceding calendar year in the Journal of Raman Spectroscopy (JRS), as well as in trends over the past decade across journals that have published papers important to the field of Raman spectroscopy. This information is obtained from statistical data on article counts obtained from Thomson Reuters ISI Web of Science Core Collection by year and by subfield of Raman spectroscopy. Additional information is gleaned from presentations at the XXV International Conference on Raman Spectroscopy (ICORS 2016) in Forteleza, Brazil in August 2016 and those featuring Raman scattering at SCIX 2016 organized by the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS) in Minneapolis, Minnesota, USA in September 2016. Coverage is also provided for topics from the conference ECONOS 2016 held in April in Göteborg, Sweden and GeoRaman 2016 in June in Novosibirsk, Russia. Finally, papers published in JRS in 2015 are highlighted and arragned by topics at the frontier of Raman spectroscopy. From these various perspectives, it is clear that Raman spectroscopy continues to be a rapidly expanding field that provides sensitive photonic information of matter at the molecular level in an ever‐widening arena of novel applications.

“…Our analysis also shows that DMA-Dy crystal should show presence of 12A 1 + 12A 2 + 12B 1 + 12B 2 , 12A 1 + 12A 2 + 12B 1 + 12B 2 , 3A 1 + 3A 2 + 3B 1 + 3B 2 , 3A 1 + 3A 2 + 3B 1 + 3B 2 and 3A 1 + 3A 2 + 3B 1 + 3B 2 lattice modes related to translations of HCOO -, librations of HCOO -, translations of DMA + , librations of DMA + and translations of Dy(III), respectively.In case of HYD-Dy, the number of internal modes of the HCOO -ions is the same as for DMADy, i.e., 96 (24A 1 + 24A 2 + 24B 1 + 24B 2 ), as presented in table S5. Free single protonated 1 hydrazine has C 1 symmetry and its 15 internal vibrations (15A) can be distributed into symmetric stretching (ν s ), antisymmetric stretching (ν as ), scissoring (δ)), rocking (ρ), wagging (ω) and twisting (τ) vibrations of the NH 2 and NH 3 groups as well as stretching NN mode [48][49][50]. For thePca2 1 structure containing four hydrazinium (HYD + ) cations, number of internal modes of the HYD + cations increases to 60 with the irreducible representation 15A 1 + 15A 2 + 15B 1 + 15B 2 .…”

We report synthesis, crystal structures, Raman, infrared, electron absorption and emission spectra of two novel luminescent MOFs, [(CH 3 ) 2 NH 2 ][Dy(HCOO) 4 ] and [N 2 H 5 ][Dy(HCOO) 4 ]. These data show that [(CH 3 ) 2 NH 2 ][Dy(HCOO) 4 ] and [N 2 H 5 ][Dy(HCOO) 4 ] crystallize in polar space groups of Pna2 1 and Pca2 1 symmetry, respectively. The polar properties of [N 2 H 5 ][Dy(HCOO) 4 ] come from the arrangement of template cations that possess internal dipole moment as well as from the symmetry of the framework. In [(CH 3 ) 2 NH 2 ][Dy(HCOO) 4 ] the Dy(III)-formate framework is centrosymmetric and polar properties of this compound arise from the arrangement of the DMA + cations. Vibrational studies reveal that position of ν(NN) band, which is very sensitive to coordination changes, is characteristic for hydrazine molecules forming onium ions. Optical studies show that both compounds exhibit emission of Dy(III) ions, in spite of full concentration of dysprosium ions in the studied compounds. Our data also show that radiative decay times, 57 µs for [(CH 3 ) 2 NH 2 ][Dy(HCOO) 4 ] and 96 µs for 2 [N 2 H 5 ][Dy(HCOO) 4 ], are very long compared to lifetimes observed in inorganic compounds. We have also preformed Judd-Ofelt analysis of the optical absorption spectrum of the hydrazinium analogue that provides information on various optical parameters such as electric-dipole oscillator strengths, Judd-Ofelt parameters Ω λ , branching ratios and spontaneous emission probabilities.

The incomplete decomposition product of metastable hydrazine (N2H4) instead of the energetically favorable ammonia (NH3) upon decompression is one drawback in applications of energetic material oligomeric hydronitrogens. We explore the stability of hydrazine molecules in hydrazine hydrate (N2H4·H2O) under pressure in diamond anvil cells (DACs) combined with in situ Raman spectroscopy and synchrotron x-ray diffraction (XRD) measurements. The results show that one NH2 branch forms NH3 group by hydrogen bonds between hydrazine and water molecules after the sample crystallizes at 3.2 GPa. The strengthening hydrogen bonds cause the torsion of hydrazine molecules and further dominate a phase transition at 7.2 GPa. Surprisingly, the NN single bonds are strengthened with increasing pressure, which keeps the hydrazine molecules stable up to the ultimate pressure of 36 GPa. Furthermore, the main diffraction patterns show continuous shift to higher degrees in the whole pressure range while some weak lines disappear above 8.2 GPa. The present peak-indexing results of the diffraction patterns with Materials Studio show that the phase transition occurs in the same monoclinic crystal system. Upon decompression, all of the hydrazine molecules extract from hydrazine hydrate crystal at 2.3 GPa, which may provide a new way to purify hydrazine from hydrate.
