By field Using AND/OR By author
This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Atmospheric chemistry of HFE-7200 (C4F9OC2H5): Reaction with OH radicals and fate of C4F9OCH2CH2O(•) and C4F9OCHO(•)CH3 radicals

Journal of Physical Chemistry a — 1998, Volume 102, Issue 25, pp. 4839-4845

Relative rate techniques were used to measure k(OH + n-C4F9OC2H5) = (6.4 ± 0.7) × 10-14 and k(OH + i-C4F9OC2H5) = (7.7 ± 0.8) × 10-14 cm3 molecule-1 s-1 at 295 K leading to estimates of ≈0.9 and 0.7 years for the atmospheric lifetimes of n-C4F9OC2H5 and i-C4F9OC2H5, respectively. A pulse radiolysis technique was used to measure k(F + HFE-7200) = (5.6 ± 2.1) × 10-11 cm3 molecule-1 s-1 (HFE-7200 = C4F9-OC2H5) at 296 K. Using FTIR-smog chamber relative rate techniques the following rate constants were determined at 296 K: k(F + HFE-7200) = (5.5 ± 1.1) × 10-11, k(Cl + HFE-7200) = (2.7 ± 0.6) ti...
