  This work presents a series of highly-accurate excited-state properties
obtained using high-order coupled-cluster (CC) calculations performed with a
series of diffuse containing basis sets, as well as extensive comparisons with
experimental values. Indeed, we have computed both the main ground-to-excited
transition property, the oscillator strength, as well as the ground- and
excited-state dipole moments, considering {thirteen} small molecules
(hydridoboron, hydrogen chloride, water, hydrogen sulfide, boron fluoride,
carbon monoxide, dinitrogen, ethylene, formaldehyde, thioformaldehyde,
nitroxyl, {fluorocarbene}, and silylidene). We systematically include
corrections up to the quintuple (CCSDTQP) in the CC expansion and extrapolate
to the complete basis set limit. When comparisons with experimental
measurements are possible, that is, when a number of consistent experimental
data can be found, theory typically provides values falling within the
experimental error bar for the excited-state properties. Besides completing our
previous studies focussed on transition energies (\textit{J.~Chem.~Theory
Comput.} \textbf{14} (2018) 4360--4379, \textit{ibid.}~\textbf{15} (2019)
1939--1956, \textit{ibid.}~\textbf{16} (2020) 1711--1741, and
\textit{ibid.}~\textbf{16} (2020) 3720--3736), this work also provides
ultra-accurate dipoles and oscillator strengths that could be employed for
future theoretical benchmarks.
