1. IR Spectral Interpretation Workshop
There is a continuing need for Fourier transform infrared (FT-IR) users to receive training in how to interpret the infrared spectra they measure, and this new column by Brian C. Smith provides practical advice about how to do this. This first installment discussed some basic IR theory and laid out a blueprint for future installments. |

2. Analysis of the State of the Art: ICP-MS
In honor of Spectroscopy's celebration of 30 years of covering the latest developments in materials analysis, we asked a panel of experts to assess the current state of the art of inductively coupled plasma–mass spectrometry (ICP-MS) and to try to predict how the technology will develop in the future. |

3. How to Design a Miniature Raman Spectrometer
In this article, we described the key factors that influence the overall size of a spectrometer, such as the diffraction grating groove density and detector size. Furthermore, we demonstrated compact Raman spectrometer designs as small as 30 mm X 30 mm in footprint. |

4. In Situ FT-IR Analysis of Soils for Forensic Applications
Although handheld FT-IR spectrometers now make it possible to carry out field-based FT-IR analysis of soils at a crime scene, reliable and tested protocols are not yet available for such work. Here, we discussed sampling options and described tests of a methodology that is being developed for in situ FT-IR analysis of soil samples. |

5. Analysis of the State of the Art: Raman Spectroscopy
In honor of Spectroscopy's celebration of 30 years covering the latest developments in materials analysis, we asked a panel of experts to assess the current state of the art of Raman spectroscopy and to predict how the technology will develop in the future. |

6. Determining Elemental Impurities in Pharmaceutical Materials: How to Choose the Right Technique
Although implementation of the new United States Pharmacopeia chapters <232> and <233> on elemental impurities has been delayed, pharmaceutical analysts should start planning now to meet the new requirements. This comparison of the capabilities of four major atomic spectroscopy techniques — flame atomic absorption, electrothermal atomization, ICP-optical emission spectrometry (OES), and ICP-MS — will help you choose the most appropriate analytical technique to meet the requirements of the new USP chapters as well as those of other analytical problems you are asked to solve. |

7. Choosing the Best Regression Model
Which regression method (or model) is better or best when compared to others? Here is a discussion of a mathematical and rational process that is useful for selecting the best predictive model when using regression methods for spectroscopic quantitative analysis. |

10. Trends in Spectroscopy: A Big-Picture Look at Recent Innovations and Future Directions
Recent federal science and technology initiatives are focusing public attention and funding on the need for innovative research in environmental quality, sustainability, medicine, and advanced materials. Spectroscopy techniques will undoubtedly play a significant role in addressing these and other global challenges. In this context, this article broadly surveyed recent trends in spectroscopic techniques and instrumentation. |

12. Resonance Raman and Photoluminescence Spectroscopy and Imaging of Few-Layer MoS2
Resonance and off-resonance Raman spectroscopy and imaging were used to examine the spatial variation of the solid-state structure and electronic character of few-layer MoS2 flakes. Simultaneous acquisition of photoluminescence spectra with the Raman scattering provided complementary ways of rendering Raman and photoluminescence spectral images of thin-film MoS2. |
