Data show similar VOpeak between incremental and verification tests in SCI, suggesting that VER confirms VOmax attainment. However, in AB participants completing arm ergometry, VER is essential to validate appearance of 'true' VOpeak.
Reaction of [XeF][AsF6] with excess KrF2 at −78 °C in anhydrous HF (aHF) solvent has yielded the first mixed KrII/XeII noble‐gas compound, [FKrFXeF][AsF6] ⋅0.5 KrF2⋅2 HF, a salt of the [FKrFXeF]+ cation. The potent oxidative fluorinating properties of KrII fluoride species resulted in oxidation of XeII to XeIV in aHF at −60 °C to form the mixed KrII/XeIV cocrystals, ([Kr2F3][AsF6])2⋅XeF4 and XeF4⋅KrF2. Further decomposition at 22 °C resulted in oxidation of XeIV to XeVI to give the recently reported KrII/XeVI complexes, [F5Xe(FKrF)n][AsF6] (n=1, 2), [F5Xe][AsF6], and a new KrII/XeVI complex, [(F5Xe)2(μ‐FKrF)(AsF6)2], which was characterized by low‐temperature (LT) Raman spectroscopy. The [FKrFXeF][AsF6]⋅0.5 KrF2⋅2 HF, ([Kr2F3][AsF6])2⋅XeF4 , and XeF4⋅KrF2 compounds were characterized by LT Raman spectroscopy and single‐crystal X‐ray diffraction. Quantum‐chemical calculations were used to assess the bonding in [FKrFXeF]+, [Kr2F3]+, and [Xe2F3]+ and to aid in their vibrational assignments.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
