Module Specifications.
Current Academic Year 2024 - 2025
All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).
As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available. Thank you for your patience and understanding.

Description This module provides an overview at, or informed by, the forefront of this field, of a number of spectroscopic techniques used in research and industry to determine the electronic, chemical and structural properties of matter through its interaction with electromagnetic radiation. The approach used is descriptive and operational. A solid understanding of the basic principles of quantum mechanics, mechanics, thermodynamics, and optics is required. | |||||||||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Develop and articulate a systematic understanding of knowledge at, or informed by, the forefront of research both qualitatively, and quantitatively of the experimental apparatus used for a selection of spectroscopic techniques, including (i) highlighting key properties needed in components of the experimental apparatus, (ii) evaluating numerically the characteristics of spectroscopic components and apparatus and (iii) evaluating numerically how the physical characteristics of the sample affect the spectroscopic features. 2. Develop and articulate a systematic understanding of knowledge at, or informed by, the forefront of research both qualitatively (phenomenologically), and quantitatively of the nature of the light-mater interaction occurring in selected spectroscopic techniques. 3. Demonstrate this systematic understanding by calculation the position of spectroscopic lines in selected spectroscopic techniques and interpreting experimental data. 4. Demonstrate this systematic understanding by calculating the material properties of a sample based on spectroscopic data for selected spectroscopic techniques. 5. Demonstrate a critical awareness of the current problems in the field by carrying out a critical analysis of current publications implementing spectroscopic techniques, analyzing both the hardware implemented as well as the data analysis and interpretation of the results. | |||||||||||||||||||||||||||||||||||||||||||
