- Abstract:
- Across several academic fields dating wood is of utmost importance. There are two different approaches being applied for dating purposes: dendrochronology and radiocarbon dating. The latter, also called carbon-14 dating, was the last advancement in this field in the 1950s. The present paper’s intent is the development of an additional method as well as the introduction into preliminary model drafts. The chemical composition of wood alters over time. Infrared spectroscopy is used to observe these changes and subsequently, enables their analysis with a regression model. Models for calibrating different types of wood, that are spruce, larch, pine and oak were developed using specimen of recent Austrian trees and timber, as well as water and salt-preserved samples. They are applicable to wood aged up to 3400 years. The calculated models enable the statistical analysis of the chemical composition via FTIR (Fourier Transform Infrared Spectroscopy) to a high degree of certainty and accuracy, evaluating samples that are few in numbers, easily attained and straightforwardly quantified.
