proton affinity造句
例句與造句
- He also developed gas phase ion chemistry bracketing techniques for determining proton affinity.
- Proton affinity 149.6 kcal / mol.
- Proton affinity, on the other hand, is not a measure of free energy.
- Rates are proportion to decreasing substrate X-O bond strength and increasing substrate proton affinity.
- This method has determined that quinuclidone ranks among secondary and tertiary amines in terms of proton affinity.
- It's difficult to find proton affinity in a sentence. 用proton affinity造句挺難的
- Atmospheric pressure DIOS was shown to be an effective tool for quantitative analysis of drugs with high proton affinity.
- Further analysis via the extended kinetic method allows for the determination of the proton affinity and gas phase basicity of 2-quinuclidonium.
- On the other hand, the compound OgH + exhibits a dissociation energy ( in other words proton affinity of oganesson ) that is smaller than that of RnH +.
- In the positive mode, the relative proton affinities of the reactant ions and the gaseous analyte molecules allow either proton transfer or adduction of reactant gas ions to produce the ions of the molecular species.
- Concurrently, the neutral analyte molecules of a sample vapor enter the flow tube, via a heated sampling tube, where they meet the precursor ions and may undergo chemical ionization, depending on their chemical properties, such as their proton affinity or ionization energy.
- An example of this is methane, which cannot be analysed using H 3 O + as a precursor ion ( because it has a proton affinity of 543.5kJ / mol, somewhat less than that of H 2 O ), but can be analysed using O 2 +.
- Superbases have also been defined semi-quantitatively as any species with a higher absolute proton affinity ( APA = 245.3 kcal / mol ) and intrinsic gas phase basicity ( GB = 239 kcal / mol ) than Alder's canonical proton sponge ( 1, 8-bis-( dimethylamino )-naphthalene ).
