Perhaps you should try some spelling variations:
"low temperature uv-laser spectroscopy" » "low temperature uv-ray spectroscopy" (Expand Search), "low temperature uv-nuclear spectroscopy" (Expand Search)
"low temperature uv-beam spectroscopy" » "low temperature uv-decay spectroscopy" (Expand Search), "low temperature uv-ray spectroscopy" (Expand Search), "low temperature uv-nuclear spectroscopy" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"low temperature uv-laser spectroscopy\") OR (\"low temperature uv-beam spectroscopy\"))~".
• Removing quotes may allow a broader search: (( low temperature uv-laser spectroscopy ) OR ( low temperature uv-beam spectroscopy ))~.
• Adding a wildcard symbol may retrieve word variants: (("low temperature uv-laser spectroscopy") OR ("low temperature uv-beam spectroscopy"))*.
