FT Raman microscopy of untreated natural plant fibres.
The application of FT-Raman microscopy to the non-destructive analysis of natural plant fibres is demonstrated with samples of flax, jute, ramie, cotton, kapok, sisal and coconut fibre. VibrationalExpand

Fourier-transform Raman spectroscopic study of natural waxes and resins. I
Abstract The Fourier transform-Raman spectra of some natural waxes and resins that have been found in preparations of archaeological material have been identified non-destructively. VibrationalExpand

Minium; FT-Raman non-destructive analysis applied to an historical controversy
The term minium was applied to both cinnabar (HgS) and red lead (Pb3O4) pigments in antiquity; in Roman times, minium was reserved for mercury(II) sulfide but was applied increasingly to leadExpand

A Critical Comparison of Some Raman Spectroscopic Techniques for Studies of Human Stratum Corneum
This study evaluates a variety of techniques and sampling conditions for Raman spectroscopic investigations of human stratum corneum. Using a Fourier-transform Raman system and samples of stratumExpand

Oxybenzone oxidation following solar irradiation of skin: photoprotection versus antioxidant inactivation.
We used noninvasive Fourier transform (FT) Raman spectroscopy to follow the fate of the broadly used ultraviolet UVA sun blocker, oxybenzone, after topical application to the skin. Our results showedExpand

Fourier-transform Raman spectroscopic study of human hair.
Fourier-transform Raman microscopic spectra of normal, untreated and bleached hair fibres are presented. Vibrational assignments are made and differences are ascribed to the production of cysteicExpand

COMPARATIVE RAMAN MICROSCOPY OF A MARTIAN METEORITE AND ANTARCTIC LITHIC ANALOGUES
The Raman microspectra of the Nakhla SNC meteorite, which probably originates from Mars, are reported here for the first time. The specimen is shown to be heterogeneous, even at a sampling level of 2Expand

Raman spectroscopic study of 3000-year-old human skeletal remains from a sambaqui, Santa Catarina, Brazil
A Raman spectroscopic study of red-pigmented human bones from a 3000-year-old sambaqui burial was undertaken for the first time. Visible (633 nm) and near-infrared (1064 nm) excitation were used toExpand

'DRAGON'S BLOOD'. I : CHARACTERIZATION OF AN ANCIENT RESIN USING FOURIER TRANSFORM RAMAN SPECTROSCOPY
Several resins generically known as ‘dragon’s blood’ from different botanical and geographical sources were characterised non-destructively using Fourier transform Raman spectroscopy. GenuineExpand
