Historical Overview of Raman Spectroscopy,28. Key landmark improvements in technique and the incorporation of novel methods of generating monochromatic radiation, imaging and the accession of scattered radiation are reviewed chronologically. The coupling of an optical microscope to a Raman spectrometer in the 1970s with the use of laser exc

From Frescoes to Paintings,troscopy to cultural heritage. The advent of a range of laser wavelengths and modern instrumentation for fluorescence background rejection has enabled a wider application of the technique coupled with the minimal sampling required for Raman microscopy. A list of pigments and dyes studied by Raman sp

Analytical Raman Spectroscopy of Manuscripts and Maps: The Role of Inks, substrates and relatively less work has been undertaken on the composition of the inks. In the case of ancient maps, the ink holds the key to much analytical information as few involved the use of pigments. This chapter traces the use of carbon-based inks through to mediaeval iron-gall or gallotann
